The Effects of Intermittent Solar Radiation in Off-grid Solar Power System A Case Study of Two Cities; Sacramento, CA and Miami, FL 'Worst Month' method
No full textThis study illustrates the impact of the solar radiation by comparing the design of two off-grid PV systems installed in two different locations have same annual average solar irradiation (insolation) values at fixed tilt angle. The case study selected the city of Sacramento, CA and Miami, FL. The monthly average Irradiation values in Sacramento are very diverse where the minimum, average and maximum values are spaced compared with the values in Miami which have no significant variation of solar irradiation from month to month. Comparing the Design of the two different systems will reflect the impact of the sporadic solar insolation on the rating values for the components of each system, which is affecting PV system cost. The design assumes the same load based and the worst case scenario of the solar irradiation. Each system will consist of PV modules, charge controller, power inverter and batteries

A New Approach for Detecting and Monitoring of Selective Forwarding Attack in Wireless Sensor Networks
No full textWireless sensor networks (WSNs) are prone to most security attacks. These attacks are such as wormhole attack, sinkhole attack, selective forwarding attack, and Sybil attack. So, each layers in WSNs has some security attacks. Sensor nodes are easily susceptible to security attacks, since deployed these nodes are unattended and unprotected. Also, limited capacity of sensor nodes accounts for the security attacks on WSNs. Applications such as military surveillance, traffic surveillance, healthcare, and environmental monitoring are impacted by security attacks. Hence, researchers have created various types of detection approaches against such attacks. Selective forwarding attack is one of an attack that is not easily detected in the networks layer. In selective forwarding attack, malicious nodes function in the same way as other nodes in the networks. However, it attempts to delete or modify the sensitive information prior to transferring the packet to other node. In this poster, we proposed an approach for monitoring this type attack in wireless sensor networks
Influence of Graphene on PCL Scaffolds for Tissue Engineering Applications
No full textAn important approach in tissue engineering is to develop suitable scaffolds with good properties which is meant for implantation. PCL is a widely used FDA approved polymer in the biomedical field. It is biocompatible, biodegradable and also has good mechanical properties. We fabricated PCL scaffolds using the electrospinning technique by optimizing various conditions to get bead free nanofibers. Nanofibers produced by electrospinning technique were characterized using Scanning electron microscope (SEM) to confirm the size, surface morphology etc. Graphene is introduced into PCL scaffolds to increase the conductivity of the scaffolds and also to further improve the mechanical properties of the scaffold. These scaffolds provide a good platform for the cells to interact well and proliferate. Impedance measurements were done for various concentrations of PCL and PCL with graphene. We found that if there is an increase in graphene concentration, there is decrease in impedance measured for the fibers. The future study would be to implant the prepared PCL-Graphene scaffolds into an animal model
The Absence of Soil-dwelling Microflora will Decrease the Fitness of Arabidopsis thaliana in Presence of Opportunistic Fungus such as Penicillium spp.
No full textTo support this claim, A. thaliana strain Col-0, was grown in either autoclaved or non-autoclaved soil and in the presence or absence of Penicillium spp. The Penicillium spp. was utilized into a cultural suspension and sprayed at the base of stems of treatments 1 and 3. The culture suspension proved relatively ineffective for the infection of healthy mature plants. However, the suspension did have a minimal effect on young still-developing plants. Autoclaved treatment had a higher mortality rate on juvenile plants than non-autoclaved treatment when suspension was applied. Illustrating that young vascular plants are more susceptible to fungal infection than mature plants
Leadership in a Turnaround Situation and a Multicultural Environment
No full textLeadership style in a turnaround situation, especially in a multicultural environment, is very important to the success of the organization. As the organization is transformed to a successful one, the leader may have to adapt his or her style. This case focuses on the leadership of a new CEO recruited to overcome a crisis situation in a small community bank. The CEO also faced the additional challenges of being from a different culture than most of his employees and of interacting with the founder and previous CEO who had quite a different leadership style. In the process of turning the bank around and implementing a new strategy, the new CEO also transformed his leadership style in order to reduce anxiety and gain the respect and confidence of the employees, the board of directors, and the community
