Digital Forensic is a branch of Forensic science that encompasses the recovery and investigation of digital devices for material mainly related to computer crime. Digital Forensic Investigation is the process of investigating digital devices for the purpose of generating digital evidence related to an incident or a crime under investigation. A proliferation in the amount of crimes and crime related...
For the convenience of users, thousands of wearable devices with new built-in applications are appearing every year in the field of healthcare, sports, and safety. However, the system of them should be operated by using limited capacity of power because of very small size of battery that can be loaded into a wearable device due to the device properties. For such a reason, Chip Vendors are recently...
In the current era of big data and data mining, efficient storage of images is very important. In the collected datasets from blogs or social network sites, images are one of the prominent part of that datasets. Images took very large space for storage and even loading when required by the third party. So, image compression is one of the important part in big data and effective data mining. These...
Twitter has evolved from being a conversation or opinion sharing medium into a platform to publicize information about high impact events. Now day's any events in the real world create a corresponding flood of tweets on Twitter, but not all content posted on Twitter is trustworthy for providing information about the event. The primary objective of this paper is to analyze the credibility of information...
Nowadays, due to busy lifestyle of people, ignorance and tolerance of symptoms, slowly develops diabetes. It cause when body stops producing enough insulin which is essential to control the blood sugar. The amount of high sugar level affects vital organs of the body like kidney, heart, and brain. The diagnosis of diabetes typically confirmed on the basis of increased glucose level in the blood. Symptoms...
Location-based social networks (LBSNs) have recently attracted millions of mobile users to share their locations and location-related contents. With the increasing use of LBSNs, an efficient personalized recommendation service is required to recommend appropriate point of interests (POIs) to users. Traditional collaborative filtering (CF) based recommendation algorithms need go through all users in...
In this paper, we propose a method to detect duplicate codes based on structure and content of control statements present in the source codes. The proposed method efficiently finds all types of clones. Similarity between two programs is identified by comparing metrics of programs. Metric of a program is computed using control statements, operators and operands present in the program. Proposed method...
Mobile hosts in a Mobile Ad-Hoc Network are linked by wireless links without usual routing infrastructure and link fixed routers. Ad-Hoc Distance vector Routing (AODV) is among one of the prominently used routing protocol for packet transfer from source to destination. It relies on maintaining most recent information, for which, each ad-hoc node maintains hop count and sequence number field. Ad-hoc...
Falling accidents cause severe damage to human health, especially to the elderly. Nowadays, smartphones are ubiquitous and widely used around the world, in which rich sensors are embedded. Thus, a smartphone based falling detection system, SmartFDS is proposed in this paper, which can recognize the associated individual's falling behavior and send out an emergent message containing the location for...
Systems chemical biology integrate chemistry, biology and computation tools as a whole system, which can help researchers to deeply study the interaction and relationship among small molecules, such as genes, proteins, targets, compounds and so on. With systems chemical biology, researchers can concentrate on new way of drug discovery, including drug target path discovery, which can not only help...
Recently it receives a great attention to reduce road accident and controlling traffic by limiting the speed of vehicles. Moving vehicle speed is usually determined by using Radar, Photo Radar, Drone Radar, LIDAR Speedometer Clocks, Average Speed Computers, Aircraft or Video frame methods, etc. Most of these methods are very expensive and also their accuracy is not quite satisfactory. In this paper,...
Motor Imagery (MI) is now highly adapted to control machine or computer by interfacing with brain or mind. This paper proposes a method to differentiate left, right and feet motor imagery movement according to two and three class classification using statistical features of the EEG signal of the subjects. For this purpose the collected EEG signals of three subjects are segmented and feed to discrete...
Sentiment Analysis (SA) is an opinion mining study analyzing people's opinions, sentiments, evaluations and appraisals towards societal entities such as products, services, individuals, organizations, events, etc. Of late, most of the research works on SA in natural language processing (NLP) are focused on English language. However, it is noted that Bangla does not have a proper dataset that is both...
The main target of the approach presented in this paper is to recognize offline Bangla conjunct characters by Stroke Matching Based Approach. At first, the approach simplifies the word into strokes. Later, it matches the strokes with the one that is stored in the dataset. The approach reduces the noise and then works over the strokes. Up to now a lot of recognizers are available to recognize BOC (Bangla...
Educational Institutions attempts to gather feedback from students' to study their sentiments towards courses and instructors and to enhance the performance of the instructors. Basically, such feedbacks are gathered at the end of the semester with the use of survey forms. However, this technique is very tedious, slow and time consuming. With the advent of social media, especially Facebook, the collection...
Spectrum of hypernasal speech produced by cleft palate (CP) speakers carries acoustic information regarding hypernasality (HP). This study compares the variation of acoustic features of HP in continuous read speech with gradually increasing severity of HP within and across gender and detect HP. Three point vowels /i/, /a/ and /u/ from continuous read speech produced by seven male and seven female...
The method of joining images to make a panorama is known as image stitching. It is an enthusiastic research area in image processing and computer vision but still a challenging problem for panoramic images. A good number of researches had been carried out to develop different algorithms for image stitching in the last few years. Image stitching approaches is classified mainly in two groups: direct...
MySQL is an open-source very popular RDBMS to store and manage data. But it faces difficulties of prolonged response time to handle big data. On the other hand, cloud is a perfect solution for managing and querying big data but it is not suitable to process small data due to delayed response time. In this paper, we propose a cloud-based solution that will improve response time and performance of the...
A flexible planar textile antenna suitable for wearable applications has been designed at 2.4GHz. The effects of the dielectric substrates of the micro strip antenna have been investigated. Such materials are: fleece, denim and Velcro. Both edge mounted and vertical mounted excitation configurations are considered. It is observed that for edge mount, micro strip line feeding, antenna with fleece provides...
An integrated current sensing circuit with incorporated comparator function is presented. The current scaling is done in two independent steps, therefore very high current division ratio is obtained, which makes this circuit suitable for converters with large output currents. The additional comparator part eliminates the need for a separate comparator circuit, therefore reduces the design effort and...
