The Smart Grid is an advanced digital two-way power
flow power system capable of self-healing, adaptive, resilient
and sustainable with foresight for prediction under
different uncertainties. Smart grid technology places
greater demands for reliability on communications
infrastructure. Due to the large number of distribution
components connected to the distribution level feeders,
a massively deployed wireless communication network is
identified as the potential technology for this application.
This paper presents a comprehensive review of wireless
communications technologies for implementation of
smart grid in a systematic way, a case study of Puducherry
Smart Grid pilot project is also presented. Various network
attributes like internet protocol (IP) support, power
usage, data rate etc. are considered to compare the
communications technologies in smart grid context.
Techniques suitable for home area networks (HANs) like
ZigBee, Bluetooth, Wi-Fi, and Z-Wave are discussed and
compared in context of consumer concerns and network
attributes. A similar approach in context of utilities concerns
is adopted for wireless communications techniques
for neighborhood area networks (NANs) which include
WiMAX and GSM based cellular standards. Smart grid
applications, associated network issues and challenges are
elaborated at the end.
Occurrence of radio trapping over West African Atlantic Ocean (WAAO) was carried out using ERA 5 hourly data covered the period of ten years (2001 -2010). Obtained meteorological data were used to calculate refractivity, refractivity gradient and modified refractivity gradient. Characteristics of radio trapping were obtained from the refractivity and modified refractivity gradient. Altitudinal distribution of anomalous radio propagation and percentage occurrence of radio trapping were obtained for ten different points on Atlantic Ocean. Diurnal and spatial distributions of different anomalous conditions were also obtained for West African and Atlantic Ocean. Values of obtained gradient were compared with ITU values. The result established the occurrence of ducting which vary seasonally and geographically across the West Africa Atlantic Ocean. The Influence of sea surface temperature on radio trapping were also examined

The transfer of information from source to destination i.e transmitter to receiver is called the communication. Basically communication is possible in two ways they are wire communication and the other one is wireless communication. The satellite communication is a best example for the wireless communication. The Satellite communication has served making in many ways from instance its is used to predict weather and broadcast storm warnings and also provides a wide range of communication services in the fields of relaying television programs, point to point communication, voice, data, internet, fax. Wireless communication is the transfer of information or power between two or more points that are not connected by an electrical conductor. The most common wireless technologies use radio waves. With radio waves distances can be short, such as a few meters for Bluetooth or as far as millions of kilometers for deep-space radio communications. It encompasses various types of fixed, mobile, and portable applications, including two-way radios, cellular telephones, personal digital assistants, and wireless networking. Other examples of applications of radio wireless technology include GPS units, garage door openers, wireless computer mouse, keyboards and headsets, headphones, radio receivers, satellite television, broadcast television and cordless telephones. Somewhat less common methods of achieving wireless communications include the use of other electromagnetic wireless technologies, such as light, magnetic, or electric fields or the use of sound.
TThe satellite communications market is growing and new generation of satellites will have unprecedented levels of flexibility and scalability: future multibeam High Throughput Satellites (HTS) are expected to be able to operate thousands of beams simultaneously. This poses new challenges when it comes to efficiently managing the increasing amount of resources. Two of these challenges are linked to the beam placement (i.e., defining the pointing direction for each beam) and beam shape (i.e., optimizing the gain distribution among covered users) problems. Optimizing these processes could reduce required RF power and enable the accommodation of new users into the system. In this paper, we present an algorithm to address the joint beam placement and beam shape optimization. It consists of an iterative approach combining a placement heuristic and a gradient descent-based method. The algorithm decides the total number of beams needed and provides their pointing directions and shapes. We analyze the performance of this algorithm in a high-dimensional scenario based on realistic operational data, considering elliptical shapes with variable semi axes and relative rotation. We show this method provides higher gain to users and reduces satellite power consumption in comparison to other approaches from literature.
Ultra wideband (UWB) technology is one of the most widely technologies used in wireless communication system to support the application that required high data rate and high speed. Since the release by the Federal Communications Commission (FCC) of a bandwidth of 7.5GHz (from 3.1GHz to 10.6GHz) for UWB wireless communications, UWB is rapidly developed to justify the needs of modern wireless communication applications. The development of UWB technology includes antenna as an essential part of wireless communication systems. However, there are more challenges in designing UWB antenna than a narrow band one. A suitable UWB antenna should be capable of operating over an ultra wide bandwidth as allocated by the FCC. At the same time, satisfactory radiation properties over the entire frequency range are also necessary. Besides that, small size, lightweight, low profile and low cost are also features highly required to be in UWB antenna. The purpose of this work is to design and fabricate ultra wideband microstrip patch antenna for wireless application with optimum performance such as wide bandwidth, good matching impedance, small antenna size exhibits and its E and H–plane radiation patterns are stable over the UWB frequency range . To achieve that, slotted partial ground plane, steps notches at the bottom of the patch and slots on the patch techniques are applied on a conventional rectangular microstrip patch antenna excited directly using microstrip line technique. Designed UWB antenna simulated using Computer Simulation Technology and fabricated on FR4 substrate. Both simulation and measurement results show that UWB antenna has good performance. Return loss results satisfy UWB technology frequency range under -10dB; from 3.23 GHz to 10.89 GHz for simulation, while measured return loss slightly shifted to start form 3.8 GHz to 10.6 GHz. Omin-directional radiation patterns in both E and H plane with sufficient gain at different frequencies in UWB frequency band. Therefore, the antenna design has to evolve to meet the new requirements. By considering the increase of low cost, compactness of electronic systems, and a need of embedding two or more narrowband systems together, microstrip patch antennas are most widely candidates used because of their several advantages such as light weight, low volume, low fabrication cost and capability of dual, triple and more frequency operations. For high data rate transmission system and multifunctional devices, we need wideband directional microstrip antennas with constant gain over the wide frequency range. Designing a low-profile directional microstrip antenna for these applications is very challenging
Asteroid mining offers the possibility of revolution supply and availability of many sources vital for human sources; also there are private companies that support asteroid mining for recognition precious metals. Hence, the new missions are defining beyond LEO, therefore light-time communication delay issues, such as time lag and low Bandwidth will prohibit this type of operation because of huge data and limitation at windows to DSN. Hence, several solutions have been considered such as use higher frequency bands direct to ground, spacecraft autonomy system, swarm small satellites asteroids prospector etc. by this way the communication is the most important subsystem for this issue, based on the previous researches for prospecting of asteroids, Ka or X band is used for direct communication to ground and S or UHF band is used for constellation. In this proposal a communication subsystem for a small-satellite (1U, 2U…) by direct communication to ground and constellation by mother ship and mining robot is investigated.

Combining topology control with network coding has been recently noticed which provides essential advantages such as lower energy consumption and higher lifetime. In this paper, we utilize optimization and graph theory to propose a mathematical perspective for combining network coding with transmission range adjustment in Wireless Sensor Network (WSN). For this aim, we define an extended optimization problem based on two vectors of variables including transmission range and network flow. In particular, it is proved that there is a coding solution if and only if the extended optimization problem has at least an optimal solution. Due to this theorem, a new objective function is provided which is more practical to prolong the lifetime of WSNs. The simulation results demonstrate that the proposed model could adjust transmission range efficiently to obtain the optimal lifetime for network-coding-based WSNs.
Increasing internet data traffic has driven the capacity demands for currently deployed 3G and 4G wireless technologies. Now, intensive research toward 5th generation wireless communication networks is progressing in many fronts. 5G technologies are expected to be in use around 2020. Moving toward 5G, network synchronization is expected to play a key role in the successful deployment of the new mobile communication networks. Synchronization is an essential prerequisite for all mobile networks to operate. It’s fundamental to data integrity, and without it data will suffer errors and networks can suffer outages. ‘Loss of synchronization’ problems can be difficult to diagnose and resolve quickly and add to operational costs. Poor synchronization affects customer satisfaction and is therefore revenue affecting too. This paper presents synchronization requirement and related aspects in upcoming 5G technologies.
As the benefits of advanced composite materials become known to the satellite communications industry, there is an increasing need for fast and accurate design and analysis of these new composite reflectors. Since often times these composite structures are used in cost critical commercial applications, which require faster design engineering, materials development, and manufacturing with shorter delivery schedules. Due to cost and time constraints, full scale environmental testing is usually not an option for these commercial applications. Therefore, there is an urgent need for experienced composite D&A engineers with an extensive background in composite materials and structures. These engineers relay on many advanced techniques and tools to accelerate the composite design and engineering process. In this thirty-minute presentation, WCA will discuss the design and analysis techniques and tools used to develop several satellite communications composite structures for this industry. The design and analysis schedule for this project was significantly reduce due to the experience of the WCA engineering team, and the access to composite materials developed for the aerospace industry
Standard Notation has built human-centered AI for some of the worlds leading companies and innovators. In this talk, we introduce ‘Lingua Franca’, our design language for human-centered AI. Lingua Franca is the culmination of Standard Notation’s work designing AI solutions for companies spanning industries, from finance to insurance, logistics, asset tracking, consumer apps, data science tools, and deep technology. Lingua Franca includes a step-by-step design process that can be adopted by any company seeking to transform their digital strategy around human-centered AI, through a set of tools and techniques that include problem definition, ideation, iterative design, data exploration, and ethics. We start by describing human-centered AI for those new to it. We then describe how AI technology has consistently failed to be human-centered, by placing other values above those of its users. We then outline Lingua Franca, and how to integrate its ideas into your organization or team in order to create technology that is more empathetic, ethical, interpretable, and ultimately more value-aligned with humans.

The robots are those machines programmed that day by day fulfill a particular function and that take shape as a fundamental part of our lives, around the world different types of robots are developed, they are built from those that are manufactured for the Industrial areas to those For Educational purposes, El Salvador for its part is not the exception, since it has inventors and researchers who have developed robotics projects of different kinds and fields of study, among them we can mention Ademir Bermúdez, who throughout the years has dabbled and driven in robotics in the country with the development of different robots some of them created at the Gerardo Barrios University (UGB) and other personal. Within the UGB, the best known robots are Robotito, Robi a robot for the social interaction of children with special needs, Alan T Robot a service robot and which is in AI processes and a robotics kit from 4 grade to University, among others.
The semi-humanoid Robot A06 arises from the ideal of the Christopher robot where each version of "A" has been printed in 3D, the latest version is in 3D printing, measures 65 cm, has two arms, waist, face and base With wheels for the construction of the robot, the next development cycle is carried out, the objective of the robot is clear.
The project aims to be a learning robot for children and young people, thereby promoting the ease of human-robot interaction through:
Minibloq, Ardublockly, Arduino, Visual Studio, Snap4Arduino, also for body movements among other languages.
The robot has sensors to interact with the environment, said electronic components known as; motion sensors, distance, colors, sound detection that interconnected with each other allow the robot to perform some activities that are executed, in turn it has two screens that allow the simulation of emotional states similar to those of the human being in order that it has a certain degree of empathy with its surroundings, so it also has a screen where it shows data captured by its sensors or other relevant information and that serves as a parameter to the human being, in the same way it has a horn for the emission of sounds with an internal memory of 16GB.
Each of its versions seeks to reach the maximum of the ideals in order to meet its development objective, it should be emphasized that the final idea is to have a functional robot, printed in 3D, easy to control and that can be programmed on different platforms.
The name is from the story of the predecessor of Astro Boy, which was called A106 or ATOM which is the goal of reaching an advanced robot in the future.
The research methodology is applied since the development of the robot is based on previous and experimental knowledge since it collects data from people who have interacted with it and its previous versions, thus working with a mixed method with a qualitative approach.
The project is still under development, some tests have been carried out with versions A01, A02, until A06, the following versions by components are on hold
DISCUSSION AND CONCLUSION: The fundamental idea was based on the robot calling Christopher and the manga ATOM INICIA, with which it is expected to have a 150 cm robot at the end of the investigation, which is programmable, friendly design and easy to use, for schools, colleges, institutes , and universities. You have a great way to go, up to an A106
For the field of AI to reach any measurable sense of maturity, we'll need methods to debug, error-check, and understand the decision-making process of machines. The lack of trust was at the heart of many failures of one of the best-known AI efforts. Artificial intelligence (AI) is a transformational $15 trillion opportunity, but without explainability, it will not reach any measurable sense of deployment. We are now entering of AI where AI systems will become capable of explaining the reasoning behind every decision made by them. The AI systems themselves will construct models that will explain how it works. XAI is all about improving trust of AI-based systems. At one end it brings fairness, accountability and transparency to the front and center of AI; and on the other end it enables us to control and continuously improve our AI systems. In this session, I will go over why the AI needs to be explainable, what does that mean, the state of the art of explainable AI as well as various approaches to build it.

Needless to say that DATA is the most important driver for data-driven digital transformation. In one of its latest reports Gartner indicates that the number of AI projects will double in 2020. Where today we have 4 to 5 AI projects per company, we go to 35 projects in 2022. The biggest challenges for the implementation of AI are the lack of specialists and, the concerns and the lack of a clear and effective framework about data quality and defining the scope.
Data-driven decision making is about decisions that are made based on insights gained from (historical) company data by applying data analytics and AI. We forget about intuition, observation or "informed guesswork": no more shooting in the dark! We say that data is the oil of the 21st century, analytics and AI is the combustion engine.
The insights gained from data can be used by companies:
- to provide valuable information to optimize their current operational efforts and thus become more customer-focused;
- to forecast future trends;
- to make them more adaptable to the constant state of change in the digital world;
- to help them developing strategies and new activities (cf. blue ocean) in order to generate more revenue.
During the presentation we will explain how we can make the traditional organization AI proof by initiating methods and techniques for the creation of company awareness about the importance of data, the setup of data maturity tracks, the improvement of data quality, "ideation" setup, etc.), and what architectural resources we need to consolidate and store company data to achieve all these and make it accessible to analytics and AI.
By the end of the session it will be obvious to the listener how decisive and how important it is to have a robust, consistent data foundation layer for obtaining reliable results through analytics and AI.
