A Spectral Estimation of Discrete Harmonizable Process

H. M. Faied, R. M. EL-Sagheer,
Abstract :
In this paper, we develop the non-parametric spectral analysis for non-stationary discrete-time stochastic processes. This development will be investigated by using the multi-tapering and averaging technique. In particular, we obtain an estimator for the spectral density function of a harmonizable time series. This estimator is constructed by dividing the available time series into a number of overlapped and non-overlapped segments and then a multi-tapering technique is applied for each segment. Also, we obtain an estimator for the auto-covariance function and another estimator for the spectral distribution function of these processes, based on the spectral density estimator. Statistical properties of these estimators are investigated, including the asymptotic behaviour of the bias and covariance.

Abstract: We demonstrated the importance of critically questioning the assumptions, rationales, and views of parents and students that shaped apartments when attending online classes during the covid-19 pandemic. It is shown that online education forms huge pressure on apartment designs, rooms’ functions and furniture arrangements. These desire and needs include technical preferences, economic aspects, and personal preferences. The following results were found: Parents and students coped with this by choosing a space that achieves the maximum benefits of the following: (i) access to natural light, room temperature, and proximity to the Wi-Fi were the most important technical preferences; (ii) regarding personal preferences respondents preferred quietness, maintaining privacy, feeling safe, and last having clear and easy access during attending online classes; (iii) in terms of the cost concerns, respondents priorities minimizing the cost by using existing furniture and planning for the potential restoration beforehand. Finally, the dilemma of temporary study place appeared during the enforcement of distant education caused by Covid-19 infection. It is a consequence of f having fixed study spaces in the existing apartment designs in Makkah, and maybe in the whole country. It is confident to stat that apartment’s occupants are able to manage and change the apartment layout to meet most of the sudden or emergency situations. However, having a work or study place right from the early stages of designing the apartment is unarguably better.

Indian Higher Education in World University Rankings – The Importance of Reputation and Branding

Ashwin Jerome fernandes, Balvinder shukla, Habib Fardoun,
Abstract :
Branding in higher education gives institutions an identity that locates them in the social world. Although the promotion of branding assists in innovative ways to promote the development of a product or service, the contribution is equally as important as recognizing that branding goes beyond the promotion. Branding essentially holds corporations and institutions, such as higher education institutions, accountable for the worth of the product or service they offer. Branding is the intangible feature an organisation or institution upholds and delivers. The implications of branding initiatives in higher education are shown to be beneficial in the overall success of an institution’s identity, enrolment, marketing strategies, and recognition. Branding is an important aspect to consider fostering the reputation of Higher Education Institutions (HEI’s). However, the process to include aspects related with branding is not an easy task. This paper describes a study of the inclusion of Branding Methodology in some Indian HEI’s.

The unilateral arbitration clause between permissibility and nullity

Nashat Mahmoud Jaradat, Ghassan JassimSarhan,
Abstract :
It should be noted that through researching the judicial applications of Arab countries on one of the issues that have occupied legal thoughts in the Western world for decades and still in one form or another, the so-called Unilateral Arbitration Clauses, we could not find a discussion about the applicability of this clause within the laws. Even though this condition takes a reasonable space of the legal arguments as previously mentioned, it has even become widely used in contracts such as tenancy, contracting, and financial investments.It was revealed through the research that the clause mentioned above, which we will discuss in detail later, has increased its use in financing contracts in recent times, especially with the increasing globalization of banking services and bank transfers. Although banks usually prefer to resort to traditional litigation, the inconsistent or more accurate, The lack of similarity in the legal rules and judicial applications related to banking transactions and their difference from one country to another was a reason for the banks preference, in one way or another, for the option of resorting to arbitration to remain an option.There is no examination for the legitimacy of an unequal or optional arbitration clause in Bahrain. Also, the Bahraini and Egyptian courts, to the best of our knowledge, until this moment, did not decide whether it should consider null or valid.The same case with the French courts, in which there are no cases that examined this type of clauses except for a case in 2006 and the other is a judgment close to the same issue on October 7, 2015, from the French Court of Cassation, which we will discuss it later.The English and American courts were a different issue. They examined this clause and have many judicial implementations, and this is due, in our opinion, to the fact that most of the arbitration terms either related to multinational companies operating within the framework of the Wall Street Stock Exchange in New York or those that stipulate the enforcement of British and Wales law on the provisions of the contract, especially that the nature of Contracting in the Anglo-Saxon system is more open and permits the introduction of stipulations and conditions that may be restricted by Roman law.Whereas many Arab countries in general, Bahrain and some Gulf countries, in particular, are seeking in their economic model to attract foreign investments and capital, especially those related to financial and banking industries, in order to diversify sources of income in local economies and one of the essential things that can be identified The decision of capital to enter the market in a country or move away from it is the judicial authority in terms of independence as well as in terms of the judicial application of legal texts, as these factors are directly reflected in the desire to invest as they clearly show the possibility of protecting investors through the judiciary or not.

Numerical solution of a space-time fractional derivative of groundwater flow equation

ABDON ATANGANA,
Abstract :
The classical Darcy law is generalized by regarding the water flow as a function of a non-integer order derivative of the piezo¬metric head. This generalized law and the law of conservation of mass are then used to derive a new equation for groundwater flow. Two methods including Frobenius and Adomian Decomposition method are used to obtain an asymptotic analytical solution to the generalized groundwater flow equation. The solution obtained via Frobenius method was valid in the vicinity of the borehole this solution was in perfect agreement with the data observed from the pumping test performed by the institute for groundwater study on one of their borehole settled on the test site of the University of the Free State. The test consisted of the pumping of the borehole at the constant discharge rate Q and monitoring the piezometric head for 350 minutes. Numerical solutions obtained via Adomian method are compared with the Barker generalized radial flow model for which a fractal dimension for the flow is assumed. Proposition for uncertainties in groundwater studies was given

Li Du,
Abstract :
Single link failure is the primary form of all kinds of network failures. Protecting survivable multicast sessions against single link failures in WDM networks has been becoming more and more important. Furthermore, measuring and improving the QoS (Quality of Service) and QoP (Quality of Protection) is of great significance to the development of multicast sessions with the enhancement of peoples consciousness of QoP and QoS. This paper studies the multicast protection approaches and algorithms based on QoP+QoS and puts forward some innovative designs. Firstly, we do qualitative and quantitative analyses about QoP+QoS. Secondly, VS_MFBG scheme based on VS (Virtual Source) is presented to save resources. What is more, we innovatively propose SDP_QPS (Shared Disjoint Paths based on QoP+QoS) algorithm. Shown in the simulation results, these designs can not only improve the rate of resource utilization, but also decrease the blocking probability and average delay.

 

Research on Interference Suppression of Pseudo-random Code Phase Modulation Fuse Based on EDTWD Analysis method

Yin Dafeng,
Abstract :
The anti-jamming ability of pseudo-random code phase modulation fuse is very strong. But the effectiveness of suppressing narrow-band interference is limited by the signal bandwidth. Thus, an effective method is developed to identify the narrow-band interference in the wide-band spread spectrum signal. Extended discrete-time Wigner-Ville distribution (EDTWD) analysis method is adopted to extract and reconstruct the narrow-band interference in the received signal of pseudo-random code phase modulation fuse. Then the interference is cancelled by the adaptive interference cancellation. The method doesn’t require any prior knowledge of interference signal, makes the received signal distorted little and can also be used in the circumstance of some interference sources. The simulation result showed that the interference signal after being separated and then synthesized had the similar frequency characteristics as before.

High Variability Resilient in Nano-Scaled Technologies for Low power 7T-SRAM Design

Shyam Akashe, Sanjay Sharma,
Abstract :
High variability in nano-scaled technologies can easily disturb the stability of a carefully designed standard 6TSRAM cell, causing access failures during a read/write operation. We propose a 7T-SRAM cell to increase the read/write stability under large variations. The proposed design uses a low overhead read/write assist circuitry to increase the noise immunity. Use of an additional transistor and a floating ground allows read disturb free operation. While the write assist circuitry provides a floating ground during a write operation that weakens cell storage by turning off the supply voltage to ground path of the cross-coupled inverter pair. This allows a high speed/low power write operation. Monte Carlo simulations indicate a 200% increase in the read stability and a boost of 124% in write stability compared to a conventional 6T-SRAM design, when subjected to random dopant fluctuations, line edge roughness, and poly-granularity variations. HSPICE simulations of a 45nm 64x32 bit SRAM array designed using standard 6T and proposed 7T SRAM cells indicate a 31% improvement in write speed, 30% decrease in write power, read power decreases by 60%, and a 44% reduction in the total average power consumption is achieved with the proposed design.
