In this article, speed of a non-linear hybrid electric vehicle (HEV) is achieved by adjusting its throttle position. Different controllers such as proportional-integral-derivative (PID), pole placement controller, linear quadratic regulator (LQR) and state observer based controller (OBC) are proposed. First, mathematical model of the vehicle is designed then open-loop stability, controllability and...
Macular Edema (ME) is the retinal disorder which is caused because of fluid deposition in the sub-retinal layers. It causes loss of central vision if left untreated. The symptoms of this disease are not apparent in early stage and as the disease progresses; it becomes very difficult to diagnose. Optical Coherence Tomography (OCT) imaging is one of the latest and efficient techniques for the detection...
This paper presents the design of multi and wide band frequency reconfigurable monopole antenna, using FR4 as a substrate with thickness of 1.6mm. The radiating element is printed on a truncated metallic ground plane. The antenna works in a single-band and two dual-band modes using two switches. The single-band (WiMAX at 3.45GHz) mode is obtained when both switches (SW1 and SW2) are in OFF state....
Language of signs is usually used by the deaf-mute persons in order to convey their message. But, it becomes very difficult for those who have no knowledge of the sign language. The aim of this research work is to resolve this problem using Digital Dactylology Converser (DDC) which is a device that converts a sign language into voice signal and text message. Primarily a hands gesture is recognised...
Network lifetime and energy consumption are major issues in wireless sensor networks while protection of the primary user is the most important activity in a cognitive radio network that necessitates the cognitive radios to detect the primary user signal promptly and accurately. We propose a network architecture that increases lifetime of the network by efficiently consuming energy and guarantees...
In these days, three degree of freedom (3DOF) cranes are considered as backbone in most of industries. It is mostly used for picking and placing of heavy objects from one place to another place. The common part in mostly cranes is jib system. Two main tasks of jib system are movement of the trolley and loading/unloading of the payload. The safety of crane mostly depends upon these sub tasks. In most...
We are living in the society of information where it is vital to communicate information as quickly and efficiently as possible. In order to improve the efficiency of telecommunication industry, latest technology of fibers has to be studied, analyzed and implemented. The journey of optical fibers to Photonic Crystal Fibers during the last few years is a positive step towards the improvement of communication...
The term “Internet of Things” (IoT) refers to the expansion of Internet technologies to include smart objects by extensive deployment of exclusively identifiable distributed communication devices. The management of configuration in these devices, in particular, is a challenge due to the high heterogeneity in different communication protocols, communication sequences, and processing capabilities. We...
Recently; medical data mining has become one of the well-established research areas of machine learning and AI base techniques have been used to solve the complex classification problem of thyroid disease. Due to the existence of non-palpable nodules it is very hard to detect the structural changes of thyroid disease by assessing the thyroid functional changes. For instance at structural level “Euthyroid”...
This paper compares the effects of ring, radial and interconnected DC grid topologies on the transient stability of a segmented 15 - bus electric grid for different HVDC schemes. For this purpose, three HVDC convertor technologies and four HVDC station configurations are considered. A three phase AC bus fault is applied and the rotor angle disturbance is analyzed. The results show that the transient...
This paper demonstrates the problem and effects of landmines in defense fields. We are proposing a robot that has the aptitude to detect the buried mines and lets user control it wirelessly to avoid human causalities. The robot is equipped with special wheels controlled by H-Bridge module, allowing it to move in all possible directions. In this paper, we focus on the safety of humans and the robot;...
Multi-document summarization aims to produce a compressed version of numerous online text documents and preserves the salient information. A particular challenge for multi-document summarization is that there is an inevitable overlap in the information stored in different documents. Thus, effective summarization methods that merge similar information across the documents are desirable. This paper...
