PERFORMANCE ENHANCEMENT BY USING OPTIMUM BEAMFORMING ALGORITHM IN COGNITIVE NETWORK

Cognitive Networks are an emerging new type of networking technology that can utilize both Radio Spectrum and Wireless Station. Based on the Knowledge of the availability of such resources gathered from past experience the resources can be utilized efficiently. Signaling is the major issue in Cognitive Network. Multiple Input Multiple Output (MIMO) technique is used for the transmission of signals in Cognitive Network. In this paper, the performance of MIMO in a Rayleigh fading environment is analyzed and water filling algorithm is used to maximize the capacity of MIMO channels we also propose an optimum beamforming algorithm to design beamforming vectors such that, interference caused by the primary transmitter to the Cognitive receiver and the interference caused by the Cognitive transmitter to the primary receiver is completely nullified while maximizing the rate of both primary and secondary links. The Proposed technique does not require any changes in the existing environment between the Primary and Secondary user. The secondary user will be allowed to transmit concurrently to the Primary user. Since the primary user is a licensed one it need not to have any Knowledge about the resources utilized and performance of the secondary user and it transmits independently. Further it is also proved that the rate of Cognitive Multiple Input Multiple Output (MIMO) link implemented by the proposed beamforming algorithms is equal to interference free Multiple Input Single Output (MISO) link.
The Chilbolton advanced meteorological radar: a tool for multidisciplinary atmospheric research

An ex-air-surveillance S-band radar was installed on the 25 m antenna at Chilbolton, near Winchester, over 20 years ago for studies of the effects of rain on communications systems. Since that time the functionality of the radar has been steadily developed to keep it at the forefront of meteorological research radars throughout the world. Recent developments have added phase and Doppler capabilities to the radar. The paper briefly discusses the use of differential reflectivity measurements in determining rainfall rates, microwave attenuation and the phase of hydrometeors. The new hardware and signal processing are described and examples of radar scans and applications of the radar are presented.
Investigation of the Flow Topology around a Simplified Two-wheel Landing Gear with Emphasis on the Stagnation Point

Experiments were conducted in a recirculating water channel to determine the flow topology around a simplified two-wheel landing gear model. Both hydrogen bubble visualization and Particle Image Velocimetry techniques were employed. The Reynolds number based on wheel diameter was 32,500. The general flow topology was characterized for several wheel configurations. Previously undiscovered structures have been found in several regions of the flow field, and their behavior was found to depend strongly on the geometry of the wheels. The phenomena of vorticity amplification near the stagnation point of the wheels was also studied. Weak upstream vorticity was found to collect, grow, and amplify into large coherent structures which then shed in a regular manner. The size, location, and shedding frequency of these structures has been characterized. The impingement point of the upstream vorticity was found to dictate the dynamics of the phenomena. %%%%MAST

Antifungal activity of MgO and ZnO nanoparticles against powdery mildew of pepper under greenhouse conditions

Powdery mildew disease of peppers (Capsicum annuum L.) caused by Oidiopsis sicula is the most damaging disease in the field and greenhouse. Chemical control has been widely used for the control of powdery mildew. To minimize the deleterious impacts of fungicides, the present study aimed to evaluate the antifungal effect of different concentrations (100, 150 and 200 mg/L) of MgONPs and ZnONPs against powdery mildew in comparison with the conventional fungicide penconazole (0.25 ml/L) under greenhouse conditions. The synthesis and characterization of MgO and ZnONPs were carried out. Dynamic light scattering (DLS) analysis revealed the presence of MgONPs and ZnONPs at the nanoscale level with a size average of 52.97 nm ± 1.43 S.D and 79.45 nm ± 1.74 S.D, respectively. Two foliar sprays were applied at two-week intervals on pepper plants cv. Dolma, naturally infected with powdery mildew in the three greenhouses of El -Dokki (GH-1), Toukh (GH-2) and El-Haram (GH3). Both MgONPs and ZnONPs markedly reduced disease severity (DS) and area under the disease progress curve (AUDPC) at a concentration of 200 mg/L. Statistical analysis showed a significant (p<0.05) difference between treatments in the three greenhouses as well as between means of combined treatments. Scanning electron micrographs confirmed that MgONPs and ZnONPs caused inhibition and alterations in the treated fungal structures. Pepper plants treated with penconazole displayed the highest peroxidase activity and recorded 1.229 ΔA422/10 sec/g FW. While, the highest polypheneloxidase activitiy was obtained by MgONPs with value reached 0.283 ΔA495/10 sec/g FW . Out of all treatments, MgONPs were the superior in increasing total chlorophyll at the three applied concentrations, with values of 74.81, 82.94, and 91.19 mg/g FW, respectively. Cytotoxic investigations exhibited the clastogenic nature of MgONPs, ZnONPs, and penconazole. The obtained results are encouraging and emphasize the recognition of MgONPs and ZnONPs as a viable alternatives to conventional strategies.
Running Head: REJECTION SENSITIVITY AND BORDERLINE 1 Rejection Sensitivity and Borderline Personality Disorder Features: The Mediating Role of Attachment Anxiety, Need to Belong, and Self-Criticism

Rejection hypersensitivity has been considered to be the core feature of borderline personality disorder (BPD) patients. However, little is known about the possible developmental mechanisms that might explain the association between rejection sensitivity and BPD features. The current study investigated the mediating roles of adult attachment, need to belong, and selfcriticism in the association between rejection sensitivity and BPD features in 256 healthy adults. Results indicated attachment anxiety, need to belong, and self-criticism mediated the association between rejection sensitivity and BPD features. However, attachment anxiety and self-criticism did not moderate the mediated association between rejection sensitivity and BPD features. The findings suggested that individuals with high rejection sensitivity were more likely to be anxiously attached to significant others, which might increase the desire to be accepted by others. To satisfy this elevated need to affiliate with others, they might become more self-critical which may contribute to high BPD features.
Climate Instability and Agricultural Productivity in Africa: Cross-Country Evidence

This paper analyzes the impact of rainfall instability on crop yield in Sub-Saharan Africa. Using a large panel of African countries over a sufficiently long period and relying on a very large dataset assembled for the agricultural sector in Africa, the paper tests whether agricultural research and development, and modern infrastructure provide such dampening effects in a context of rising climate instability and stagnating farm productivity in Africa. The results demonstrate a key and robust effect of greater investments in agricultural science and technology in dampening the effect on the link between rainfall instability on crop yield volatility in Sub-Saharan Africa. Effort should therefore be on boosting the availability of researchers specialized in agricultural science and technology and on agricultural infrastructure such as irrigation to help farmers cope better with the increased risks stemming from global warming.
Representation of the Anomalous Magnetic Moment of the Muons via the Einstein-Podolsky-Rosen Completion of Quantum into Hadronic Mechanics

In this paper, we briefly review half a century of research by various authors in the axiom-preserving completion of quantum mechanics into hadronic mechanics according to the 1935 Einstein-Podolsky-Rosen argument that “quantum mechanics is not a complete theory” (EPR argument). Said completion is intended to represent extended-particles in conditions of deep EPR entanglement with ensuing potential as well as contact non-Hamiltonian interactions represented by the new operator T̂ in the associativity-preserving products A ? B = AT̂ B of hadronic mechanics. We recall that muons are unstable and decay spontaneously with a mean live τ = 2.19703×10−6 s, thus suggesting that they are composite, and therefore extended particles with constituents capable of triggering their decay. We then assume that the physical constituents of the muons are the ordinary electrons released in the spontaneous decay with low mode μ− → e−, e, e−, resulting in the structure model according to hadronic mechanics (hm) μ− = (ê↓ , ê + ↑ , ê − ↓ )hm where the “hat” characterizes iso-renormalizations due to nonHamiltonian interactions. We show that the indicated hadronic structure model achieves an exact representation of all characteristics of muons, including rest energy, charge radius, mean life, spin, charge, spontaneous decays and anomalous magnetic moment.
MOLLUSCICIDAL ACTIVITY OF GROUND CHERRY (PHYSALIS MINIMA LINN.) AGAINST GOLDEN APPLE

The search for efficient, organic, and environment-friendly molluscicide that could minimize the spread of the invasive Golden Apple Snail (Pomacea canaliculata) in the Philippines is still on going. This study was conducted to identify the lethal concentrations of the crude extracts of P. minima as potential molluscicides. Snail mortalities were compared between each plant part and snail species and LC50 and LC100 values for the plant part tested were recorded. The most toxic part of P. minima extract against the Golden Apple Snail was the roots (7.43 ml l -1 ) followed by the stem (9.65 ml l -1 ) and the least toxic was the leaves (10.93 ml l -1 ) after 24-hr median lethal concentration (LC50). Based on the 24-hours lethal concentration (LC100), the part with the greatest molluscicidal effect on Golden Apple Snail was the roots (17.47 ml l -1 ) followed by the stem (21.02 ml l -1 ) and the part with the least molluscicidal effect was the leaves (24.84 ml l -1 ). The result obtained showed that the roots extract was more susceptible to the death of snail species Pomacea canaliculata. Comparing the LC50 and LC100 the roots extract showed the highest molluscicidal activity followed by the stem bark and leaves extracts. Therefore, this study indicated that ground cherry plant extracts possessed molluscicidal effect for controlling the golden apple snail.
PRIVACY PRESERVING LOCATION BASED SERVICES QUERY SCHEME BASED ON FULLY HOMOMORPHIC ENCRYPTION

Location-Based Services (LBSs) are increasingly popular in today’s society. LBSs are used in a broad variety of applications such as social networks with location sharing. LBSs can help people enjoying a convenient life and has attracted considerable interest recently. However, the privacy issues of LBS are still challenging today. Usually LBS Providers (LBSPs) offer user privacy protection statement to assure users that their private location information would not be given away. However, many LBSs run-on third-party cloud infrastructures. So, the privacy is still in a big problem. While a large number of privacy-preserving solutions for LBS have been proposed, nowadays most of these solutions do not consider the fact that LBS is typically cloud-based. Aiming at the challenges, in this paper, we present a new efficient Privacy Preserving LBS Query scheme based on Fully Homomorphic Encryption ( PPQ_FHE ). In PPQ_FHE scheme, the LBSP’s data are outsourced to the cloud server in an encrypted manner, and a registered user can get accurate LBS query results without divulging his/her location information to the LBSP and cloud Server Provider (CSP). Specifically, based on improving FHE over Advanced Encryption Standard (AES). We provide a security analysis to show that PPQ_FHE scheme preserves privacy in the presence of different threats. PPQ_FHE analysis and evaluation results demonstrate that proposed PPQ_FHE scheme can preserve the privacy of the LBS users in an efficient and secure way. The results prove the feasibility and efficiency of PPQ_FHE scheme in terms of query's response time, query accuracy, throughput and query overhead.
Design and Implementation of Photovoltaic Single Stage Inverter Connected to Grid

Photovoltaic system that connected to grid is a system which applied for an area that can be reach by transmission line. This system as a support for conventional generating system. If there is a power from PV system, then power demand supplied from photovoltaic generating system. Otherwise, power demand supplied from conventional generating system. As a support conventional generating system, there is many methods to convert photo energy into AC system that connected to grid. One of conventional methods as a two stage inverter, this methods need two process to convert photovoltaic into AC system. First stage, conversion photovoltaic power to DC system. In this stage PV processed by buck boost converter. Second stage, that DC power from first stage changed into AC power system. This two stage process has low efficiency, so we try to make the process simply and more efficiency. New method called single stage inverter can be applied. With this methods, conversion DC power system from PV can be done by single stage process. From this single process, we expext that more efficiency can be achieved.

UTILIZATION OF GINGER AS A NATURAL ANTIOXIDANT AND ANTIMICROBIAL IN BAKERY PRODUCTS

This study was achieved to evaluate the Ginger (Zingiber offcinale Roscoe) as chemical composition, minerals content and fraction and identification of phenolic acids and flavonoids compounds by HPLC. The results showed that the ginger had rich in various nutritional compositions like protein, crude fiber, vitamins and minerals content. Results from HPLC found that the major and medium compounds from phenolic acids were pyrogallol, vanillin, p -hydroxbenzoic acid and pcoumaric, gallic, alpha-coumaric, ferullic,catechol, caffeic, chlorgenic and salcilic acids. Meanwhile flavonoids compounds were hispertin,kampferol, narengin, rutin, apegnin, rosmarinic, quercetin, luteolin and hisperidin compounds. Ginger was partially substituted with wheat flour at different levels 5, 10 and 15%, to produce butter cake and biscuits then sensory evaluation and anti-microorganisms during storage period (four weeks for butter cake and six weeks for biscuits) were estimated in bakery products. From the results, it could be found when added 5.0 and 10.0 % ginger to wheat flour give acceptability butter cake and biscuits. Meanwhile when add high concentration 15% ginger give not acceptability in the bakery products. Moreover when added ginger to butter cake and biscuits and the results during storage period found that the ginger had natural compounds as antibacterial and antifungal. Therefore it could be recommended that the butter cake and biscuits with ginger until level 10% give bakery product the best acceptability and antibacterial and fungal.

Climate Change and Migration in West African Coastal Zones

Global trends in migration show a predominance of internal over external flows. The African continent is the world’s most vulnerable region to climate change due to its higher levels of exposure and its scarcer financial resources for adaptation. Therefore, climate change presents in Africa some peculiar challenges to livelihoods, and security. In this paper, we assess the climate-induced migration in African coastal zones, accounting for many different factors such as conflict, demography, social networks, economic opportunities, and geographical factors such as the terrain. We also provide a critical review of major strands of models of climate-induced migration, namely agent-based models, choice-centred models, gravity model, and household allocation models. The most used data in climate change analyses are also analyzed.

DBD is known to generate non-thermal equilibrium plasma even under atmospheric pressure. DBD is suitable for ozone production [4-7]. However, some of ozone generator configurations generate inhomogeneous heating of the dielectric barrier resulting in low ozone production efficiency. Experimental studies regarding the construction of the ozone generator such as electrode arrangements[6-10], dielectric material [11], chamber geometry[12-17], power source construction [18-20], gas type (dry air or oxygen) [11], feed gas flow rate and operation pressure [21] have been extensively studied to obtain an optimal level discharge conditions for highthroughput ozone production. Ozone is created when diatomic oxygen (O2) is exposed to an electrical field or ultraviolet light. Exposure to these high levels of energy causes a portion of the diatomic oxygen molecules to split into individual oxygen atoms. These free oxygen atoms combine with diatomic oxygen molecules to form ozone. DBD ozone chamber is a device which consists of air or oxygen gap between two conductors. One of the two conductors will be coated with a dielectric material. A high Designing of Single Switching DBD Ozone Generator
The effects of continuous improvement in nursing quality on patients with cerebral hemorrhage accompanied by present-on-admission pressure ulcers

Objective: This study aims to explore the application of continuous quality improvement in the nursing (CQIN) of patients with cerebral hemorrhage accompanied by present-on-admission pressure ulcers (POAPU) and its effects on risk events, neurological function, and the prognostic survival of the patients. Methods: A prospective analysis of 174 patients with cerebral hemorrhage accompanied by POAPU was conducted, with the patients were randomized into a control group (81 cases which received routine nursing) and an experimental group (93 cases which received CQIN based on routine nursing) using a random number table. The rehabilitation of cerebral hemorrhage, the improvement of POAPU, the incidence rate of risk events, the nursing satisfaction score, the ability of daily living (ADL), and the neurological function recovery were compared between the two groups. The patients were followed up for 2 years, and their 2-year survival was recorded to evaluate their prognoses. Results: The effective rate of rehabilitation of POAPU in the experimental group was significantly higher than it was in the control group (P<0.01). The incidence rate of risk events in the experimental group was 1.08%, significantly lower than the 8.64% in the control group (P=0.017). The nursing satisfaction score in the experimental group was 87.24±6.17 points, significantly higher than the 75.33±8.04 points in the control group (P<0.001). Compared with the control group, the patients in the experimental group had significantly higher ADL scores (P<0.001) but significantly lower National Institutes of Health Stroke Scale (NIHSS) scores (P<0.001). The 2-year survival rate in the experimental group was 79.51%, significantly higher than the 51.40% in the control group (P=0.04). Conclusion: CQIN improves the rehabilitation, neurological function, and the daily living ability of patients with cerebral hemorrhage accompanied by POAPU and reduces their adverse events, so it has a great application value.
