In the present work, we study the dynamics of QD semiconductor laser under optical feedback such as the time behavior of the carriers in wetting layer, the output photons intensity and Occupation probability for the QD active region. When studying the effects of these variables the dynamics are more complex when increasing the optical feedback strength and linewidth enhancement factor at different values of time delay. These dynamics are appeared the nonlinearities and chaos behavior output of laser and these results agree with other results of other researches

This study is aimed at examining The Effect of Information and Communication Technology on Organization Performance in Banking Industry. Implying that the introduction of Information and Communication Technology in banking services has a positive effect in the development and growth of the organization. Also, to indicate that customers are their asset and the best possible way to satisfy them is to give them the best services. Based on the result, it was observed that information and communication technology leads to efficient and effective performance of banks and information and communication technology leads to competitive advantage over others and thus increases banks profitability

High peak-to-average power ratio (PAPR) problem encountered in the transmission of modern communication signals such as orthogonal frequency division multiplexing (OFDM) is solved by Crest factor reduction (CFR) techniques. They reduce the magnitude of the less frequent peaks occurring in the signal and achieve lower PAPR, Peak Cancellation Crest Factor reduction (PC-CFR) is a relevant CFR technique that is capable of large PAPR reductions while EVM and spectral mask constraints are met. In this paper, we generate the PC-CFR algorithm and simulate this algorithm to show that it is a practical technique that can be readily implemented. More than 5dB of PAPR reduction can be achieved with this algorithm

A portable and compact system based on a He-3 gás tube (LND, USA; model 25311) with an sensitive area of approximately 250 cm² and covered with paraffin (9 cm) was used to detect and monitoring neutrons at ground level in the energy range up to 10.0 MeV, during January 2015 to march of 2015 in São José dos Campos, SP, Brazil (23° 12’ S, 45° 52’ W). The detector and other hardware instruments are housed in an air-conditioned room placed near ground level. Neutron counts were accumulated at 1-minute intervals continuously. The months of January/March 2015 were normal with respect to rainfall, being with driest and wet altering days in the region. Rainfall and cloud coverage were also normal and temperature reached record levels (30° C). Coincidentally, the average neutron counts for driest days (0.2 neutrons/minute) were also low compared with other rainy days showing the presence of induced cosmic ray neutrons up to 10,0 MeV energy. The measurements and FFT analysis of the data in this three months also show that neutron counts present a daily periodicity and that the peak occurs approximately when the sun is at its highest elevation (zenith) in the sky. This indicates that the neutrons are produced by cosmic rays and that they are not related to the presence of clouds or lighting discharges. Previous studies carried out by our research group in 2010-2014, in the same months, have observed that cloud coverage modulates neutron counts at this location in tropics.

Traditionally marine transportation was separated from the importance of the transportation supply chain logistics network, but in the early 2000s became a very important aspect of the entire logistics chain operation, i.e. an integral part of the bigger picture logistics and supply chain operation. Accordingly, the port was transformed from a monopolistic market to a competitive market which inherently forces the ports to compete to offer some profitable services for instant the transhipment of container trade and that carries the burdens of additional services for improvement at ports so that they can compete. The rapid growth of seaborne trade, container traffic keeps growing parallel with the increasing of ships size; therefore it became not economically feasible to ships to load and discharge in multiple ports. Hence, some of the ports began to grow until it became what is known as hub ports. This led to the development of new types of special container transhipment port, where the transhipment define as the act of shipping goods to an intermediate destination prior to reaching their ultimate end-use. Transhipment is a common practice with logistic benefits, but can be used to illegitimately to disguise the country of origin or intent of the Goods ("How to Import into the US," 2007). The world transhipment trade is divided into nine main regions almost covering the entire world (Russo & Musolino, 2013). Our study will focus on the competitiveness of the main hub ports in the Mediterranean region where the Mediterranean`s location connecting the trade between the Middle East, Asia and Africa – and for some vessels, even USA east coast-means that regions hosts a great number of transhipment ports, a large numbers of ships calling in the Mediterranean are on the route to ports not necessarily to be their final destination for unloaded the cargo (Lloyd’s List, 2015), vis-à-vis port of Port Said whereas the port recorded a significant growth at the last years in parallel with the growth of transhipment trade in mega hubs in the Mediterranean region whereas recorded strong growth in container traffic in the recent years, recording growth well above the market average (Lloyd`s List, 2014) but at same time port Said port still so far from the Global competition. Our study will use SWOT (Strengths, Weaknesses, Opportunities and Threats) analysis for understanding the weaknesses and strengths to identifying both opportunities and threats and analyse the logistics and marketing factors influencing the growth of Port Said port in order to make recommendations on how to maintain high rates of growth and to be a global leader as integrated logistics hub in the presence of competitive market in transhipment of container trade
