Abstract :

This paper address recent developments on auxiliary power unit for dual supply unmanned aerial vehicles. The proposed APU is designed and developed as a scalable backup power solution to tethered UAV systems. The APU addressed in this paper consist of off-line battery power supply and a high speed fault detection and switching unit, to control the proposed APU. Target operation of APU is to switch the battery power whenever the primary cable power is unavailable and switch back to cable power whenever the cable power is available during the UAV flight mission. The switching speed of newly developed prototype in this research with high speed logic ICs and n-channel MOSFETs is proved to be within milliseconds range and therefore could be considered fast enough for low altitude hovering missions. The outcome of the proposed design is also compact and light weighted, hence making the proposed prototype applicable in many existing battery powered UAVs for hybrid use.

Title : Angiotensin II Delays The Extinction of Active Avoidance in Rats The Role of Transmitter Receptors

Abstract :

The extinction of active avoidance behaviour in rats following the intracerebroventricular (ICV) injection of different doses of angiotensin II (Ang II) was studied. The influence of antagonists of different neurotransmitter receptors on the effects of Ang II was also followed. Ang II induced a delay in the extinction in a dose-dependent fashion (U-shaped curve). When the animals were pretreated with different receptor blockers in doses which themselves had no action on the extinction of active avoidance behaviour, the action of Ang II on this paradigm was completely blocked  by saralasin, haloperidol, bicuculline, atropine, naloxone  Phenoxybenzamine,  propanolol and methysergide were ineffective. The data suggest that Ang II delays the extinction of active avoidance behaviour, and that angiotensin, dopamine, GABAa, opiate might be involved in this action.

Abstract :

Supply chain finance, as a kind of innovative financial products, has attracted extensive attention of the industry. In the context of capital operation, it is the most important to study the supply chain finance. Adopting content analysis method, this article combs the research on factors that affect supply chain financial service pricing from six dimensions of Supply Chain Finance: risk, return, regulation, guarantee, customer relationship and macro policy, expects to provide a theoretical basis for enterprises to set the loan price, and some guidance for financing enterprises to choose appropriate products.

Title : Delay of GeoX/Geo/1 N-limited Nonstop Forwarding Queue

Authors : Yutae Lee

Abstract :

Nonstop forwarding is designed to minimize packet loss when a management system fails to function. A system with non-stop forwarding can continue to forward some packets even in the event of a processor failure. We consider a GeoX/Geo/1 N-limited nonstop forwarding queue. In this queueing system, when the server breaks down, up to N customers can be serviced during the repair time.The delay distribution of customers is given by matrix geometric analysis.

Abstract :

We consider a queueing system, consisting of a Poisson input stream and a single server. The server is subject to breakdowns. The failed server requires repair at a facility, which has an unreliable repair crew. The repair crew also subjects to breakdown when it is repairing. We obtain the availability and the delay distribution of the queueing system.

Abstract :

The receivables arose after small and medium-sized logistics enterprises supplied manufacturer with services, which influenced the operations of the logistics enterprises. In order to alleviate the capital pressure of small and medium-sized logistics enterprises and promote the sustained and good development of supply chain, in this paper, we take the financing advantage of supply chain finance and design the model of receivables financing of small and medium-sized logistics enterprises based on the supply chain finance theories, using the Stackelberg model and inferring the optimal pricing and the optimal profit of the bank and the Small and medium-sized logistics enterprises, And carry out data simulation. All these can provide the small and medium-sized logistics enterprises with a cost-effective financing program.

Abstract :

The incidence of esophageal cancer patients who have undergone distal gastrectomy is increasing recently. Distal gastrectomy is a good model for studying the clinical effects of duodenal content reflux.Individuals with a history of gastrectomy often suffer from sever alkaline reflux esophagitis. A history of gastrectomy is associated with an increased rate of lower third esophageal squamous cell carcinoma.Therefore,I made a rat model, a total gastrectomy followed by esophagoduodenostomy(n=27)was performed to induce chronic duodenal content reflux esophagitis. Esophageal squamous cell carcinoma (SCC) (40%)developed in places distant from the anastomosis compared to Esophageal adenocarcinoma (ADC) (30%). This means that histological features may depend on the volume of reflux contents; small amounts of reflux causes SCC and a large volume of reflux causes ADC.I concluded reflux of duodenal contents developed not only ADC but also SCC from clinical and experimental data.

Abstract :

In this Paper, a monopole patch CPW fed Wi-Fi antenna is designed with complete mathematical calculations and the results are simulated using HFSS software with an operating frequency of 2.4  GHz. The antenna has a low profile and is nearly is four times smaller in size than a conventional patch antenna. The designed antenna is compared with previous designed rectangular patch antenna [2] .Wi-Fi is a wireless      networking technology that allows computers and other devices to communicate over a wireless signal, it is also used to create a wireless LAN .Wi-Fi antenna are used at both 2.4GHz and 5 GHz. The Wi-Fi frequency is highest frequency on the mobile phone among all the application frequency. As the Microstrip patch antennas are small in size, light weight and integrated easily on device. The performance of the antenna is evaluated using ANSYS HFSS.
