Paralleling source code is the
most common approach to optimize the performance of Android applications
on multi-core processors. However, the problem of selecting a good
parallel structure and its parameter tube is still a challenge. This
paper proposes the performance optimization method based on selecting
the best parallel configuration including the parallel structure and
corresponding parameter tube. Native C/C++ code of an Android
application is analyzed to find parallel structures using OpenMP
framework and parameter tubes of each parallel structure. The evaluation
function is built to evaluate the performance of an Android application
under parallel configuration. This function is implemented in an
optimization program to select the best parallel configuration of the
Android application.
Development of mobile applications brings new challenges in possibilities for their adjustment to actual context of a user and a device. Our long-term goal is to design and implement amobile client which can dynamically adapt to the surrounding conditions and requirements of the user . The operability is desired to remain even in situations when the Internet connection is lost (e.g. during natural disasters) and the mobile device should work offline
Such client is called an m-client - an application running at the mobile device which is implemented as a client with variable thickness. It is able to reconfigure itself on demand in a way that its business logic gets new functions (without the necessity to restart the application or to manually install a new module). The m-client is able to communicate with the remote server and can also become a local server itself. This approach enables miscellaneous service delivery to modern mobile devices . Arms10 - Android
Related work on dynamic loading mainly focuses on protection of intellectual property based on copy-protection. Jeong et al. show a solution that splits apllication into two parts; Incomplete Main Application and Separate Essential Class (SEC), while SEC is loaded dynamicaly and encrypted on per-user basis in order to avoid copying. Tsai et al. proposes similar solution. In contrast to this work our approach to dynamic modules loading is focused on downloading additional (optional) application modules without interaction with user and employes existing mechanisms in the Android platform for this special task
Even after the introduction of
Android Runtime (ART) in the latest release of Android Lollipop, Android
Operating System still struggles in areas such as application launch
time, especially during sluggish or memory crunch situations. When a new
application is launched in a sluggish condition, low memory killer
(LMK) gets initiated in order to free some memory by killing the already
running applications. The current LMK approach kills application based
on how recently it was used. This approach does not consider various
other user scenarios such as how frequently the application was launched
or how important that application is to user. In our proposed solution,
we aim to improve user experience by reducing or removing the delay at
memory crunch situations with efficient use of LMK.
Market share for android smartphones have been increasing exponentially day by day. With this increase in numbers of phones sold every year, even the demands for a better quality of the android phones are increasing in the competitive market. To meet the high expectations of users, companies are putting good amount of efforts in the improvement of hardware as well as software. While smartphone hardware market is already saturating to an extent, there is a lot of scope for improvement on software design on top of Google’s stock Android for better user experience.
As far as user experience is concerned, application launch time is one of the most important performance parameter for any smartphone device. In general, due to the usage of many applications, a good amount of RAM gets consumed resulting in phone sluggishness. This sluggishness is very much visible to the user especially when a particular application, which user wanted to re-use, is already killed by LMK. In our proposed solution, we intend to provide a better user experience by improving LMK’s algorithm based on user’s usage of various applications. Thereby, enhance user experience by decreasing application launch time of favorite applications Android PHP Projects - Students Projects
Android operating system has an in-built task killer, called low memory killer (LMK). The LMK keeps an eye on the real time RAM usage of all applications. Whenever excess of RAM is consumed, the LMK starts killing applications to free-upsome memory . For the killing of applications, LMK has defined some set of priorities through oom_adj value. This oom_adj is set by android kernel for each process on the Android system. It ranges from -17 at the highest to +15 at the lowest. Therefore, in memory crunch situation, LMK is called and it starts killing applications from the lowest oom_adj i.e. oom_adj value of +15. For this paper, we target only the cached applications that range from +9 to +15. As important applications and services have higher priority than cached applications, so we need not worry about them.

Quality Function Deployment (QFD) is a well-known concept that has
proved its applicability in several domains to enhance quality of
designing and manufacturing products while reducing design time and
cost. The main idea behind QFD is to listen to customers' requirements
and translate these needs into design characteristics. In this paper, we
provide an analytical approach of the use of QFD in the domain of Web
services. Specifically, we are looking on Web service description which
is the main artifact that is used to describe Web service quality
characteristics and then retrieve those Web services.

The development of the web technologies and the increasing of available
services have introduced the issue of the selection of the most
appropriate service among a set of candidate web services. First of all,
the services offering a given functionality are discovered. Then, the
service section process assists users in choosing the services that
better meets their preferences. These preferences are generally,
expressed as potentially objective functions often conflicting. Most of
existing works trying to select the best web services are based either
on a single evaluation criterion or, at best, on the use of an
aggregation function like weighted sum of several quantitative
evaluation criteria, or the use of the Pareto optimality notion. The
work presented here addresses these shortcomings by introducing a new
optimality notion based on two tests: (i) concordance and (ii)
discordance tests. It presents an efficient algorithm to select only the
best services using the introduced optimality notion. Moreover, the
proposed algorithm exhibits encouraging results as supported by a series
of experiments.

Smart cities integrate multiple mobile or web
solutions to build a comfortable human habitation. One of these
solutions is to provide an environmentally friendly, efficient and
effective garbage management system. The current garbage collection
system includes routine garbage trucks doing rounds daily or weekly,
which not only doesn’t cover every zone of the city but is a completely
inefficient use of government resources. This paper proposes a
cost-effective mobile or web based system for the government to utilize
available resources to efficiently manage the overwhelming amounts of
garbage collected each day, while also providing a better solution for
the inconvenience of garbage disposal for the citizens. Garbage
Management System Project This is done by a network of smart bins which
integrates cloud-based techniques to monitor and analyze data collected
to provide predictive routes generated through algorithms for garbage
trucks. An android or web app is developed for the workforce and the
citizens, which primarily provides the generated routes for the
workforce and finds the nearest available smart bin for citizens.
The concept of abstract services has been widely adopted in service
computing to specify the functionality of certain types of Web services.
It significantly benefits key service management tasks, such as service
discovery and composition, as these tasks can be first applied to a
small number of abstract services and then mapped to the large scale
actual services. However, how to generate abstract services is
non-trivial. Current approaches either assume the existence of abstract
services or adopt a manual process that demands intensive human
intervention. We propose a novel approach to fully automate the
generation of abstract services from a service community that consists
of a set of functionally similar services.
websites are not only be accessed by computers with a large screen.
They were mostly accessed via mobile devices such as tablets and
smartphones that relatively have smaller screen size. Almost every
website has their different style and visual appearance concerning
content and information delivery. Even though they were visually looked
different, they were mostly designed and developed by using one of one
column, two columns, or three columns layout. The way to properly
deliver content and information on a smaller screen size becomes a
challenging matter. Responsive Web Design approach allows a single web
page to be differently visualized based on the screen size of the
accessing device. Such layout changing may affect the amount of
information to be displayed on the screen, hence affecting the
effectiveness and efficiency of information delivery in a web page. This
study compares the effectiveness and efficiency of a web page that is
being displayed on a computer screen, tablet, and smartphones. How the
implementation of Materials Design Guidelines and User-Centered Design
approaches in the design process may affect the effectiveness and
efficiency of content and information delivery of a web page on smaller
screens were also evaluated and presented. This research shows that User
Centered Design and Material Design Guidelines improve the
effectiveness and efficiency of content delivery on both tablet and
smartphone. Materials Design Guidelines provide better usability
improvement than User Centered Design approach for the smartphone screen
regarding content delivery efficiency for web pages designed in three
columns layout.
The UCD approach focuses on systems development being driven by the user’s requirements instead of technical requirements. Design should depend on measures of how well the product has been used by highlighting user’s interaction and by making use of an iterative prototyping development process. When the methodology is applied to the user as the center of application; the users must be identified and analyzed by the user modeling. A user model has to be an integral part of any interactive system. A user model is different from both the actual knowledge possessed by a user and knowledge employed by system designers .
There are several modeling techniques: user roles, user segments, extreme characters , personas, etc. User roles and user segments are not particularly useful for developing user scenarios and for accommodating different users in a single project. Extreme characters is not a method that makes possible the characterization of real system users. By comparison, personas is a better modeling method based on the identification of characters who typify the system end user
Persona can clear the process which includes determining the functions and content of software and determining their priority. Persona plays an immeasurable role to make decision in advance. When determining the qualitative features and functionalities, persona can be used in brainstorming, to determine the priorities, to guide site structure, content and design. In brainstorming, discuss all the possible features, functionality and content based on the persona's goals, views and behaviors. Through brainstorming, get a list of user functional requirements. By grading the each potential function with persona, it’s very easy to get scientific evaluation results that will be used to sort the all functions by their priority.
The design of Web page should be Internet-user-oriented. The key factor
of a successful Web page design lies in that the designer can find out
counterparts of products in the real world. Another important factor of a
successful-designed web page is that the designer can represent the
products by a combination of harmonious and inducing colors, images and
characters. The pluralistic society nowadays brings about individual
aesthetic need. A unique and individualized emotional design of a web
page can impress Internet users deeply, initiate Internet users to click
promptly and contribute to the establishment of social image and mutual
communication service via a website. This thesis mainly deals with
color emotion, image emotion and character sign emotion in Web page
design. Through a typical example of a Web page design in a Web site,
the aesthetics and application of visual signs of a web page is
discussed. The emotional design of colors, images, and character signs
of a web page are studied. Click Here
Previous study showed that visual and layout are two important influencing factors on web page design Customers may stay or leave those web sites depend on the first impression with the appearance on the web page. Existing work has been performed to study some features of web page format and location appearance on the screen. studied the location occurrence of e-commerce web sites component but did not perform to the other features, nor identify the good design in the e-commerce web sites. . only identified the general web site pattern but did not consider the good design pattern in e-commerce web sites. illustrated that high aesthetic treatment in the web sites will present a professional look and feel appropriate for organization. considered web page segmentation to five blocks for improving search engine techniques. Their results showed better performance when using web page segmentation compare with un-segmentation. implemented VIPS algorithm for segmentation web page by using Dom tree technique and visual format in the web page. Dom tree is initially introduced for representation HTML object rather than semantic or visual meaning. adopted VIPS algorithm for extraction of the product information of e-commerce web sites.
In this section, we organize the web page format before performing classification algorithms. Two steps are used for our preparation. The first step is web page segmentation for dividing the main page into five blocks According to web page segmentation , we can divide the main web page into five blocks: top, bottom, left, right and center as . Hence, we can investigate area relationship of each block within web page. Apart from dividing web page, we consider the important location which is related to e-commerce web sites for using location description. In fact, there are various designs for different e-commerce Web sites. The previous study showed the attracting components on the appropriate location such as main navigation on the top or left, “about us” navigation on the bottom and advertising on the right or top center of the screen. We analyze and synthesize them to the web template. We also identify each area portions of navigation bar, product index, customer service bar, content, news and advertisement. Read More
User-Centered Design is a user-centric approach that focuses on user's needs, behaviors, wants, and limitations in the software development process lifecycle. When end users were involved in the design process, they will help to reduce the lag in information system's usability by focusing on making a product that fit user needs rather than forcing users to change their behavior to accommodate the product . Material Design Guidelines (MDG) is a design language developed by Google in 2014 that provides best practices on how to put user perception and high level of accessibility into a mobile UI design. MDG allows a user to experience a unified experience across different platforms and devices regardless the screen size of all devices in the hope that users will get a better engagement, better UI/UX and cost-effective with the products . Both UCD and MDG offer a better user experience in using a product, hence making a product quality better.
The quality of a product can be measured by its effectiveness and efficiency . The effectiveness of a product is one variable that determines the success of a product . In assessing software product usability, its effectiveness and efficiency of use need to be measured. This research will try to describe how a web page layout transformation on a responsive web page may affect its usability. This study will also try to explain how UCD and MDG will improve the effectiveness and efficiency of content delivery of a web page when it comes to a tablet or smartphone screens. Click Here
Responsive Web Design (RWD) is taking HTML5 and CSS3 web technologies into account in building a responsive web page or front-end layout. Responsive web design uses three main ingredients, i.e., a fluid and flexible grid-based layout, flexible images and media, and a module from CSS3: media queries [1]. Fluid layout assigns relative units to the page elements instead of absolute units like pixels or points. In RWD, the design of a web page can respond to user's needs by adapting it to the constraints of the browser window or device that renders it. Therefore, RWD ensures a web page screen-layout, texts, images, navigation elements, video players, and other UI elements will re-adjust themselves.
mages, videos, and other media types need to be scalable, changing their size as the size of the viewport changes. One quick way to make media scalable is by using an element's max-width property with a value of 100% or specifies the width of the content area as percentages of its viewport [8]. By doing so, when the viewport gets smaller any media will also be scaled down following its container width. Media queries make possible to switch between different style sheets based on the features of the device in which the webpage is rendered, mainly the width of the screen. MoreDetails
ln the present day scenes women safety isconsidered to be the major
problem in both urbanand rur al areas. I t is quite difficult to change
themind-set o f the entire society, but we can provideseveral security
devices f or the women who are facingsexual harassment, acid attacks,
molestation, etc. Forproviding the security, various smart devices
andapplications were developed. Many smart devicesand applications are
also available in the market; but,it doesn’t provide an effective
solution. Experts fromvarious field discovered women’s safety device
whichworks in both manually and automatically. Thisarticle examines
various women safety relatedtechniques. The drawbacks and opportunities
inwomen’s safety devices are also discussed.
Internet o f things (IoT) is influenced with human life in both
knowingly as well as unknowingly. With a help of internet every machine
is controlled, which makes the people life easier. Nowadays girls were
not permitted to move freely in the streets where they abused by
strangers. Parents are distressing about their safety which has become
the first barrier to send t hei r daughters outside. Gradually the women
harassment have been rises. Safety is the most required power for
everybody in today’s world in current generation. In our Country, even
though there is an economic development, but still there are many crimes
happens against women. I n general 86% o f working ladies in India,
facing an obstacle which is greater in Delhi, Mumbai, Hyderabad,
Kolkata,Chennai and Pune, comparatively to other places. Technology is
the finest way to achieve their security. With the help of IOT we can
control and access the machines and things whi ch are connected to the
internet even the distances are too long. Code Shoppy
Without the human-human and computer- human interaction, we can send
and receive information. B u t the harassments, rape, acid attack are
not reduced still.In order to make them safe, a smart device are
developed. Women safety device is specially designed f o r women in case
o f dangerous and emergency situation. The women safety devices should
be very simple, easy to carry and that should be integrated with several
functionalities. The smart phones usage has been drastically increased
in the world. There are several mobile applications and smart devices
are developed by the government and people in order to help the women
when they are in the trouble. Even though, they developed various
devices and applications the rate o f the sexual offenses has not been
decreased. The women safety devices or application should be combined
with a several features which are used in day today life and real
emergency cases
I n a country, Sexual offense happens against to the women and
children. According to National Crime Records Bureau , New Delhi;1. In
2011, over 42968 the criminal assault to women has increased to 84746
cases in 2016.2. Around 309 acid attack cases are produced in the year
2014.3. I n 2011, 24206 rape cases have been enlarged to 38947 cases i n
20164. According to this statistics, around 92 women’ s are raped every
day i n IndiaThe mobile application and smart devices are produced in
the women safety are:A. NotificationNishant Bhardwaj et al., [1]
proposed A Women Safety Device which gives the basic idea of Suraksha
which provides a warning to the police by giving an instant location
when distressed v ic ti m takes place. So the incident could be
prevented.As same as Nandita Viswanath et al., [2] in this article, a
small and low cost device is developed. This device is clipped to the
footwear and i t is triggered automatically when the tapping occurs
behind the other foot four times. The tapping sound is detected by the
light blue bean which is aurdino microcontroll er. Then, the message is
send to the four contact list through the Bluetooth. Naive Basye
classifier is used to analyses the walking and tapping data. By this
technique, accuracy is measured. This device is only useful for a
trained data.Similarly D. G. Monisha et al., [3] Proposed a system which
contain a location tracking mechanism, i t works i f the suffered
person press a single click it sends a SoS message with current location
to pre-set contact o f every 2 minutes, i f the person clicks a button
double times then i t records and sends SOS message and also i t cal ls
to the pre-set contact numbers when the person pressed a button for a
long time.Likewise Dhruv Chand et al., [4] proposed a WoS application is
developed. In this application it requires some basic information about
the user and the emergency contact list. When the person feel some
crisis happens against to them, a not if icati on is send to the
enlisted contacts b y shaking their phone consecutively 40 times (i.e.
upto 8 seconds) or pressing the panic button which is present in the
screen B. Location TrackingVallidevi Krishnamurthy et al., [5] proposed a
work with a women safety application. The mobile application is
developed with a help of object- oriented manner. When women are in
travel form one place to another, she has to activate the continuous
global position system GPS. The GPS continuously tracks their respective
location. In the case o f the danger when she doesn’ t mark herself
safe in particular duration then the SMS alert is send to the registered
contact.Similarly Dantu Sai Prashanth et al., [6] In this article an
application is developed with unique features and all the existing
features has been integrated to make efficient software which is useful
for women safety. This application consists o f dynamic GPS tracking
system and i t also includes spy-camera which is useful to record the
incident .Initially it requires login details and the user has to update
their information from time to time. In this, user has to be registered
to a firebase database wh00ich is used f o r user login authentication
which keeps application more secure. When the user is moving from one
place to another a GPS tracking system is switched on and thus the live
location is also viewed. I t also offers various functionalities like
first aid information, toll free call which is inbuilt. Through dynamic
GPS tracking system the enlisted contacts users who all use the same
application can view the user’ s location.Likewise Sankalp Mehta et al.,
[7] proposed an application. This application gets activated by shaking
the phone .Then the location is identified by GPS and the location is
shared to the emergency contacts. It also provides calling facility,
whenever the guardian phone is in silent mode. Thus i t provides a
calling and message facility to protect them from the incident.C.
Sensors usedPiyush Kumar Verma et al., [8] In This the proposed system
deals with a device which is used for women to protect them from
dangerous person while they are moving out in night and f o r an
independent women also i t is useful. I t consists o f buzzer, pulse
sensor and switch. When the switch is pressed, the device sends a
current locati on o f the women to all the registered contacts and i t
also monitors the pulse rate o f a women. I f the pulse reading is
abnormal, then SMS is sends to a hospital .Thus, the device is used to
protect themselves from a danger and i t is small in size.Similarly
Muskan et al., [9] Describes the women safety device which senses the
human body temperature and heartbeat pattern. The normal heartbeat and
the body temperature are stored in the cloud. When the human heart beat
rate and the temperature are changed, i t denotes that they are in the
trouble Here they use a machine learning algorithm to collect the data.
The collected data is compared with the data which are already stored in
the cloud, when change occurs current locati on o f the women is sent
with the help o f Zigbee mesh network. I t is defined as sending o f
message without the internet access, as zigbee mesh network sends a data
with the help of multiple hop distance.As same as the above work Kal
pana seel amet al., [10] The articles portrays about the safe and
secured electronic framework for women or children which involves an
Arduino controller and sensors, the several sensors used in this system
are temperature, flex sensors, MEMS accelerometer, pulse rate sensor and
sound sensor. The gadget detects body parameters like heartbeat rate,
changes i n temperature, movement o f v i c t i m by flex sensor by flex
sensor and MEMS accelerometer and the voice o f the injured individual
is detected by sound sensor and the locati on is send to the registered
contactsD. Video capturingMohamad Zikriya et al., [11] Gadget is used in
the project. I t is used to capture the image of the culprit who makes a
distrust motion to the independent women, children. Thus the captured
image is sent to the registered email ID. By using the captured image we
can able to find the distrusted person.Similarly, Jismi Thomas et al.,
[12] Proposed the system with a security devices called T o U C H M E N o
T . This portable device is attached to the clothing. This device
consists o f button which is integrated with two modules. The first
module contains a camera which records the short videos to capture the
assailant. The second module is used to send the current locati on to
the f a mily or friends.Likewise Pragna B R et al., [13] a device is
developed. I t consists o f a four button (i.e. red, green, yellow,
blue) .Each button represents one functionalities to protect the person
who is in danger. Red is used for triggering alarm, blue is used to
sending messages, green is used to record audios and yellow is used to
detect hidden cameras. Thus by pressing the various colour buttons the
women can be protected for that instant.
From the above table II, different techniques are proposed to
safeguard the women; those techniques had their own drawbacks;• It is
quite impossible to use a mobile phone during an emergency situation.•
The literature depicts that there are auto detection women safety device
based on parameters such as voice recognition, temperature heart beat
rate are exists, still these system may have a chance o f failure due to
women abnormal health condition.• Though the location is shared to the
faraway people it proceeds time to reach the spots.
We use Li-Fi Transceivers placed at both trimmings of the corridor
and on the cart to assemble material on the appearance/exit status of
the cart and the bay certification. Moreover the locating of these Li-Fi
Trans- earphones on the shop cart and on the pathways will be crucial
to the correct working of shop cart. Further, as Li-Fi equipment works
on line of eyesight, it is main to ensure that there is no obstruction
in the entry or exit of each aisle. All the product material is stored
in a folder at a central server with the location data IP. We will
record the ID, appellation and the price of the product. Li-FI
transceivers are used to inimitably ascertain products.

Li-Fi stands for Light-Fidelity. Li-Fi expertise, proposed by the
German physicist—Harald Haas, provides program of datathrough brightness
by transfer data complete an LED light bulb that diverges in power
sooner than the hominoid eye can follow. This paper efforts on evolving a
Li-Fi based system and studies its act with respect to prevailing
technology. Wi-Fi is great for general wireless coverage within
buildings, although Li-Fi is ideal for high stupidity wireless data
reporting in restricted area and for sacking receiver prying issues.
Li-Fi runs improved bandwidth, efficiency, proximit and safety than
Wi-Fi and has now realized blisteringly high quickness in the lab. By
leveraging the low cost nature of LEDs and lighting units there are many
occasions to deed this midway, from public internet access done street
