A New Design of Dual-Band Microstrip Patch Antenna for Wireless Communication

communication devices will aim to provide image, speech and data anywhere around the world at any time. This shows that the upcoming communication terminal antennas must meet the requirements of wideband to effectively cover all the possible operating bands. The aim of this paper is to improve the bandwidth and return loss of a Rectangular Microstrip Patch antenna using EBG structure on ground plane. EBG structures are periodic arrangement of dielectric materials and metallic conductors on ground plane of antennas. Microstrip antennas mounted can radiate only a small amount of its power into free space as more power leakage through the dielectric substrate. To enhance the efficiency of the antenna, the propagation through the substrate must be restricted so the antenna can radiate more power towards the main beam direction and hence enhance its efficiency. For designing this, we uses CST software tool. The designed antenna offers much improved bandwidth of 51.2 MHz and return loss of -15.15 dB at 2.446 GHz & bandwidth of 77.4 MHz and return loss of -39.02 dB at 3.8875 GHz as compared to conventional rectangular microstrip patch antenna which having bandwidth of 26 MHz and return loss of -19.16 dB at 1.806 GHz & bandwidth of 28 MHz and return loss of -14.24 dB at 2.2677 GHz respectively.

Method to control the output power of Laser in the variation of Ambient Temperature

This paper presents a method to control the output power of Laser in the variation of ambient temperature. The circuit was designed using a feedback loop to maintain a constant optical power in the presence of temperature variation. It has been shown that the small variation in the photo-detector current, in response to a small variation of the laser output power, the PI controller adjusts the bias voltage so that the current through the laser remains constant. As a result, the output optical power is kept constant. The OptiSpice software has been used which incorporates equations governing optical components directly into an electrical stimulation.
Empowering Secondary School Teachers Through Administrative Tasks

One prevalent problem confronting small schools is the unavailability of non-teaching staff that can serve the school in its financial and reportorial matters. This study looked into the need of small schools to establish their own school organizational staff that would aid the school head to be efficient in the financial and reportorial matters. This scenario is evident in Buhatan National High School (BNHS) where the school head delegated administrative functions to teachers. This case study described the present school organizational staffing, existing and preferred cultural organization (OCAI), the level of effectiveness of the present school staffing (using SEAI by Durrant and Holden) rated by the three groups of respondents --the administrator and faculty, PTA officers and SSG officers of BNHS and the significant difference in the rating of the three groups of respondents using ANOVA. It was found that the school is observing an organizational staffing where teachers take academic and administrative roles as initiated by its school head. Clan is their existing and preferred organizational culture. It also revealed that the school’s level of effectivenessis highly effective. And, the responses of the three groups of respondents were statistically different.
Design and Implementation of 9-Bit Modified

Wallace high-speed multipliers use full adders and half adders in their reduction phase. Half adders do not reduce the number of partial product bits. Therefore, minimizing the number of half adders used in a multiplier reduction will reduce the complexity. A modification to the Wallace reduction is presented that ensures that the delay is the same as for the conventional Wallace reduction. The modified reduction method greatly reduces the number of half adders producing implementations with 42 percent fewer half adders than standard Wallace multipliers, with a very slight increase in the number of full adders. Wallace multipliers perform in parallel, resulting in high speed. Reduced Complexity Wallace multiplier will have fewer adders than normal Wallace multiplier. In both multipliers, Carry propagating adder is used, at the final stage which contributes to delay.
OPTIMAL POWER ALLOCATION SCHEMS FOR DECODE-AND-FORWARD MIMO-OFDM RELAY SYSTEM

Cooperative relaying strategies have become a major topic in the wireless research community and that decode-and-forward relay technology can suppress noises effectively. In order to achieve the maximum capacity of the system, the optimal allocation algorithm is proposed under the assumption that all nodes know accurate channel instantaneous state information (CSI). Because it is hard to obtain a general solution expression during deducing, we provide an iterative power allocation algorithm with a simpler structure. Numerical results show that adopting the proposed power allocation algorithm, the capacity of MIMO relay channel with DF relay scheme can improve 1.4 bps/Hz. Through analysis, a proper iterative precision value can be found to keep the good balance between system capacity and complexity. To further improve the system capacity, we use the subcarrier pairing strategy before power allocation.
Improved Space Time Block Coding Diversity Technique for Rayleigh Fading Channel in Wireless Systems

— Numerous diversity techniques are used to minimize BER in wireless systems. But, the most effective diversity technique is Space Diversity. Space diversity is utilization of Multiple antenna systems (Multiple Input, Multiple Output - MIMO), which gives a significant enhancement to data rate and channel capacity. Multiple antenna technology can also be used to increase the data rate (spatial multiplexing) instead of improving robustness. Space Diversity is used to overcome the effect of fading . In this paper, Receive diversity is used i.e. using single antenna at Transmitter side and multiple antennas at Receiver side. So, the impact of MIMO system over different modulation technique is analyzed and the performance of the system is evaluated as Bit Error Ratio.

Non-Invasive Assessment Of Blood Flow Index In Healthy Volunteers Using Impedance Plethysmography

Background: Impedance Plethysmography (IPG) is a simple, low cost and non-invasive tool to assess the central and peripheral blood flow in human body. The literal meaning of IPG is "Recording of instantaneous volume (of an object) by measuring electrical impedance. " There are various physical and physiological factors influencing blood flow and to ensure similar responses across institutes, each institute must establish its own normative values to screen or investigate Peripheral vascular diseases (PVDs) Goal: To set up a normative baseline data of Blood flow index (BFI) for cardiovascular laboratory in department of Physiology, Government Medical college, Bhavnagar, Gujarat. Method: The study was carried out in different segments of upper and lower extremities of healthy volunteers of different age groups of either sex on Nivomon Series computerized software of L&T Company. Results: Arterial parameters measured were Basal impedance (Z0) & Blood flow index (BFI) and analyzed statistically. Body mass index (BMI) had correlation with Z0 and BFI. Conclusion: Z0 increases as the age increases and BFI remains more or less same throughout the age groups with higher BFI in upper extremities than in lower extremities. It is suggested that IPG may become an important clinical tool to study the central as well as peripheral blood flow. This simple, harmless, inexpensive, objective and non-invasive hemodynamic test may replace other invasive hemodynamic test for screening Peripheral vascular diseases (PVDs) at any age provided that one has predetermined normative data.

Multidrug Resistance Transporters and Implications on Drug Development

Multidrug resistance caused a disaster on the effective treatment of cancers and infectious diseases [1,2]. It is appalling that the current pace of drug development still could not overcome this problem, so we will continuous to lose the war on combatting cancers and infectious disease [2]. The solution may be to fully understand the molecular mechanisms of multidrug resistance and how they can be handled. There are many mechanisms involving in multidrug resistance, but multidrug transporters which are integral transmembrane proteins play a major role to medicate multidrug resistance [2]. Multidrug transporters can transport cytotoxic chemicals and compounds from cells can confer multidrug resistance. In other words, it is easy to remove drugs which are uptake into cells and drugs could not exhibit their functions.
Determinants of Income in the Informal Sector: A Case of Selected Slums in Ghana

This paper investigates the determinants of income earned in two informal slum economies in Ghana, using OLS regression analysis. Amongst factors, operator’s social networks, locus of control, type of economic activity, educational level, age of business and labour size, it was found that labour size was the main determinant of average daily income in slum activities in Ghana, with a 25% increase in average daily income for every extra person employed. Also, an extra year of experience in running the same business increases income by 10%. This reflects that, a slum operator’s continuous operation (learning and earning by doing) over the years, helps to augment income. An extra year of formal education on the other hand only increases daily income by 1%.
Timely and Secure Data Transmission in Disruption Tolerant Networks

— Disruption Tolerant Networks (DTNs) consist of mobile devices that contact each other opportunistically. In this paper, propose the original approach to support cooperative caching in DTNs, which enable the sharing and coordination of cached data among multiple nodes and reduces data access delay. The fundamental idea is to intentionally cache data at a set of network central locations (NCLs), which can be easily access by other nodes in the network. Propose an efficient method that ensures appropriate NCL selection based on a probabilistic selection metric and coordinates multiple caching nodes to optimize the tradeoff between data accessibility and caching overhead. The selected NCLs attain high chances for prompt response to user queries with low overhead in network storage and communication. A utility-based cache replacement scheme to dynamically adjust cache locations based on query history, and this scheme achieves good tradeoff between the data accessibility and access delay. A Contact Duration Aware Approach a novel caching protocol adaptive to the challenging surroundings of DTNs. To derive an adaptive caching bound for each mobile node according to its specific contact pattern with others, to limit the quantity of information it caches. In this way, both the storage space and the contact opportunities are better utilized. Extensive trace-driven simulations show that our cooperative caching protocol can significantly improve the performance of data access in DTNs.
