Large sparse second order index-1 descriptor systems arise in various disciplines of science and engineering, such as constraint mechanics or multibody dynamics, mechatronics (where mechanical and electrical elements are coupled), but also RLC circuit design. Simulation, controller design and design optimization are only some applications of such models. Either of these tasks, just like any other...
Routing messages in sparse and intermittently connected networks is one of the major challenging issues in Delay Tolerant Networking as an end-to-end path between the source and the destination is absent most of the time. To deal with this problem a wide range of routing protocols have emerged over time. One such protocol is MaxProp — which prioritizes both the schedule of packets to be transmitted...
The School bus routing and scheduling can be treated as a multi-objective Vehicle Routing Problem (VRP) that helps to transport the students in the safest, most economical and convenient way. The objective of this paper is to optimize the overall transportation cost by minimizing the fleet of vehicles and time spent in the journey. In this research, a Geographical Information System (GIS) based solution...
In this paper the impact of exponential correlation model on massive multiple input multiple output (MIMO) channel estimation is analyzed using a large number of antennas in the base station (BS) and a user terminal. We consider pilot-based channel estimation in the UL channel. The Linear minimum mean square error (LMMSE) estimator is used to investigate the effect of correlation factor on the average...
With the emergence of a promising technology, Cloud Computing is spreading its usage everywhere. Mobile Cloud Computing (MCC) integrates cloud computing with mobile devices which holds a promise to run powerful and resource-intensive applications on mobile devices irrespective of its performance limitations (e.g., battery life, memory utilization and computation). Overcoming of these limitations is...
The ability of Ethernet Ring Protection Switching (ERPS) to provide carrier grade switchover has made Ethernet technology viable in telecommunication carrier networks enabling network operators to replace SONET/SDH/PDH. Adaptive modulation (AM) is another evolution in technology which may effectively double the capacity of microwave links in favorable weather condition. In this paper, we propose an...
Location-based social network (LBSN) services are being popular at recent times. These are being manifested as service tools for different purpose of our daily lives. One very important aspect of these LBSNs services is to promote the business and help users to find their desirable location to visit. In this project, our aim is to find out the Foursquare venue popularity in Taiwan and compare its...
Video surveillance system is widely adopted in order to secure life. This paper presents embedded home surveillance systems to detect intruder in home environment. Proposed system works on embedded Linux board which is equipped with an ordinary web camera. At software level, it uses Open Computer Vision library to detect intruder in two different steps, Histogram of Oriented Gradient and Haar Like...
A compact antenna with ultra wideband characteristics is proposed which covers the dimension of 23 × 21 mm2. It has a rectangular slotted patch with a circular slot, microstrip feed line and a tapered slot ground with a thickness of 1.6 mm which covers the inexpensive FR4 dielectric substrate. The proposed antenna covers a wider bandwidth of 10.1 GHz (2.90–12 GHz) with stable radiation pattern and...
The agriculture sector is the backbone of an economy which provides the basic ingredients to mankind and raw materials for industrialization. With the increasing number of the population over the world, the demand for agricultural products is also increased. In order to increase the production rate, irrigation technique should be more efficient. The irrigation techniques used till date are not in...
Application of e-commerce has become an integral part of marketing due to an increasing diffusion of information and communication technology (ICT) throughout the world including Bangladesh. Due to its growing significance to the economy, it is critical to identify factors affecting customers' intention to use e-commerce in Bangladesh. This study used Technology Acceptance Model (TAM) to determine...
Automatic control system for robotics is getting popular day by day because of its incredible reliability and especially for the time optimization capability with performance. In this paper, the implementation of a room cleaning robot is presented which has been developed using the Arduino Uno platform with control ability by cell phone from any distance using DTMF technology. It is an electronic...
Today humanoid robots are being exhibited to redact various task as a personal assistant of a human. To be an assistant, a robot needs to interact with human as a human. For this reason robot needs to understand the human gender, facial expression, facial gesture in real time. Ribo — A humanoid robot build in RoboSUST lab which has the ability to communicate in Bangla with the people speaking in Bengali...
Recognition of handwritten numerals has gained much interest in recent years due to its various application potentials. Bangla is a major language in Indian subcontinent and is the first language of Bangladesh; but unfortunately, study regarding handwritten Bangla numeral recognition (HBNR) is very few with respect to other major languages such as English, Roman etc. Some noteworthy research works...
The concept of energy sustainability has been recently introduced in complex cyber-physical systems innovation studies. Previous empirical studies have only focused on the coordination of systems in a large system, but less research has been done on energy efficiency and management towards sustainability. We argue that in terms of energy consumption, a system comprising variety of technologies and...
Automatic prediction of continuous level emotional state requires selection of suitable affective features to develop a regression system based on supervised machine learning. This paper investigates the performance of low-level dynamic features for predicting two common dimensions of emotional state, namely, valence and arousal instantaneously. Low-complexity features are extracted from audio and...
Road traffic congestion remains a global phenomenon that causes great problems in the cities of the world; especially developing countries, resulting in massive delay, unpredictable travel times, increased fuel consumption, man-hour and monetary loss. In order to get a better solution, one of the preposition is to divert traffic to less congested route. One of the solution of collecting road traffic...
