Paraconsistent Annotated Logic Algorithms Applied in Management and Control of Communication Network Routes

This paper presents a computational method based on non-classical logic dedicated to routing management and information stream control in communication networks. Paraconsistent logic (PL) was used to create an algorithmic structure whose main property is to accept contradiction. Moreover, a computational structure, the denominated paraconsistent data analyzer (PDAPAL2v), was constructed to perform routing management in communication networks. Direct comparisons of PDAPAL2v with a classical logic system that simulates routing conditions were made in the laboratory. In the conventional system, the paraconsistent algorithms were considered as binary logic gates, and in the tests, the same adjustment limits of PDAPAL2v were applied. Using a database with controlled insertion of noise, we obtained an efficacy of 97% in the detection of deteriorated packets with PDAPAL2v and 72% with the conventional simulation system. Functional tests were carried out, showing that PDAPAL2v is able to assess the conditions and degradation of links and perform the analysis and correlation of various inputs and variables, even if the signals have contradictory values. From practical tests in the laboratory, the proposed method represents a new way of managing and controlling communication network routes with good performance.

Performance evaluation of mixed SCTP and TCP traffic over last hop wifi

The use of the internet has increased significantly with the continued increase in wireless communication devices. Recently, there is a large number of research contribution focused on Stream Control Transmission Protocol (SCTP). Multi-homing is an important feature of SCTP which improves the communication performance by usage of multiple paths during association establishment, and it can bring significant improvements of throughput. In this thesis we evaluate the performance of SCTP and TCP traffic in the WLANs and we investigate the SCTP multi-homing to improve the communication performance in WLANs. We conducted some experiments to evaluate the performance of SCTP multi-homed host under various channel bit rates and mobility speeds. The results indicate that when the intensity of background traffic increases the SCTP multi-homed host with higher channel bit rate has better performance. In addition, the SCTP multi-homed host with using lower mobility speed has higher performance (throughput, delay and packet loss).

Multi Machine Power System Stability Enhancement Using Static Sychronous Series Compensator (SSSC)

These days, the requirement for flexible and quick power stream control in the transmission framework is foreseen to increment later on taking into account utility liberation and power wheeling prerequisite. Diminishing the compelling reactance of lines by series remuneration is an immediate approach to build transmission ability. Nonetheless, power move capacity of long transmission lines is restricted by dependability contemplations. On account of the power electronic exchanging abilities as far as control and fast, more focal points have been done in FACTS gadgets regions and presence of these gadgets in transient security during transient flaws bringing about progress in power framework solidness. In this examination, a static synchronous series compensator (SSSC) is utilized to research the impact of this gadget in controlling active and reactive powers just as damping power framework motions in transient mode. The Proportional-Integral Controller (PI) controller is utilized to tune the circuit and to give the zero sign blunder. Static Synchronous Series Compensator (SSSC) is series reactive power remuneration to a power framework. The yield of a SSSC is series infused voltage, which leads or slacks line current by 90°, in this manner copying a controllable inductive or capacitive reactance. SSSC can be utilized to lessen the line impedance and upgrade the active power move ability of the line. With the boundaries and control, the SSSC is discovered successful to direct load voltage during abrupt difference in the heaps. The SSSC additionally furnishes stable activity with dynamic enlistment engine load and mitigates the insecure and swaying conduct that is coming about during the activity of remunerated Alternator with dynamic engine load.

Cloud Oriented Integrated Composite Services over SOA in Distributed Computing

Service-oriented architecture (SOA)[1] is an incessant term to deal with various administrations dependent on solicitations of various clients in various ongoing applications. Still, now, a few people don't have total information about what SOA really has done, they get confounded how SOA identifies with distributed computing. On account of cloud administration usage in SOA need security mindful help creation with finegrained stream control to make sure about web administrations at execution time to share various administrations to various clients in dispersed condition? Routinely various models were acquainted with investigating secure web administrations at execution of various administrations. Because of access control infringement, they will take high execution time and other leader boundaries profoundly, and furthermore they don't control access assurance arrangements in composite administrations, which may deliver bothersome information spillage. To conquer these infringement issues in SOA, we present Integrated Novel Multi-Level Composite Service Model (INMLCSM)[2] to lessen infringement calculation cost dependent on customer authentic and demonstrate customer composite administrations and furthermore perform nearby/distant strategy calculation for highest customers. We acquaint idea of change factor with characterize halfway administrations. Our proposed approach portrays forceful exploratory outcomes.

Isolation, characterization and in vitro anti-salmonellal activity of compounds from stem bark extract of Canarium schweinfurthii

Background Bacteria belonging to the Salmonella genus are major concern for health, as they are widely reported in many cases of food poisoning. The use of antibiotics remains a main stream control strategy for avian salmonellosis as well as typhoid and paratyphoid fevers in humans. Due to the growing awareness about drug resistance and toxicities, the use of antibiotics is being discouraged in many countries whilst advocating potent benign alternatives such as phyto-based medicine. The objective of this work was to isolate, characterise the bioactive compounds of Canarium schweinfurthii; and evaluate their anti-salmonellal activity. Methods The hydro-ethanolic extract of Canarium schweinfurthii was fractionated and tested for their anti-salmonellal activity. The most active fractions (i.e. chloroform and ethyl acetate partition fractions) were then explored for their phytochemical constituents. Fractionation on normal phase silica gel column chromatography and size exclusion chromatography on Sephadex LH-20 led to the isolation of four compounds (maniladiol, scopoletin, ethyl gallate and gallic acid) reported for the first time in Canarium schweinfurthii. Results Result indicated that scopoletin and gallic acid had greater activity than the crude extracts and partition fractions. Among the isolated compounds, scopoletin showed the highest inhibitory activity with a MIC of 16 μg/ml against Salmonella Typhimurium and Salmonella Enteritidis. Conclusions The overall results of this study indicates that the hydro-ethanolic extract as well as some of isolated compounds have interesting anti-salmonellal activities that could be further explored for the development of potent therapy for salmonellosis. Furthermore, the study adds credence to the folkloric applications of the plant.

Surgical management of the patient with factor V deficiency: a case report

<p class="abstract">Factor V (FV) is a rare bleeding disorder that its incidence is one in a million. Patients with FV deficiency have typically mucosal bleeding and prolonged bleeding after an invasive procedure. There are no certain treatment modalities and there is no product of FV concentrates in the markets. The bleeding diathesis and protect the ovarian viability are a challenge as an opposite situation for treatment options and ovarian preservation after detorsion is controversial. We aimed to provide ovarian blood-stream, control bleeding and protect thromboembolism from the patient with all of our treatment in the light of literature and a few case reports. </p>
