Cable Distribution systems - an essential element of the global information society

Not long ago, before the advent of cable operators, here in Macedonia, especially in the smaller towns in this area in the developed countries was overwhelming. In Shtip were able to follow only two or three programs in the Macedonian Television. Later, in the nineties of the last century, there have been two more programs to private local television stations. Admission to these programs is done through external antennas. Nevertheless, due to the specific configuration of the terrain and tall buildings, it was not possible quality reception of TV programs in all parts of the city. On the other hand, this way of receiving television programs by external antennas (and several antennas for each family) and brings other problems. Among other things, in terms of aesthetic appearance of buildings resembling a "forest" of antennas. With the advent of cable operators, this picture changes significantly. At the beginning of its development, the cable operators only offered a service to its customers - analog TV. Today, cable operators offer more services, ie services, and are called Multi Service Operators (Multi service operator - MSO). They invest in quality and expensive equipment that receive and distribute to end users a number of TV and radio channels channels with high quality. Users however, relatively inexpensive monthly fee can enjoy the quality of TV channels, radio channels, internet, telephony and other interactive services. Today through KDS can carry more than 70 (seventy!) Analog television and radio programs as well as a much larger number of digital TV and radio channels. Additionally through KDS enables fast digital communication, access to high-speed, broadband Internet and fixed telephony. Modern cable distribution systems represents a form of electronic communication networks. Electronic communications networks other than cable can be partially or completely wireless

The recovery of the biomass waste for industrial pellets by recycling

The biomass as an organic product which may be used as a fuel - biofuel or the raw material in the industry. The bio-fuel may be occurred as a plant or animal origin. These may be used by their direct combustion. The most effectively usefull method for biomass utilization is finalization in the pellet product as combustion product. The pellets have had appropriate parameters with geometry, caloric power, ash and dust. These wood products are rescent fuels produced by wood waste

Reverse logistics – possibility, expectation and sustainability perspectives

Reversible logistics are complex to manage due to the uncertainty involved the range of quality products, product return time, and return volume. Product returns are usually from the first days of trading, originally marked as the starting point of reversible logistics (RL). In the eighties, many researchers1 tried to formulate definitions of reversible logistics, although they2 defined it in a very limited way, ie in the material movements from customers to manufacturers, which means that it is only in terms of product returns3. Reversible logistics itself has attracted the attention of academics since the early 1990s. Reversible logistics is considered to be much more complex than a traditional supply chain.4 It includes product return, source reduction, recycling, material replacement, material reuse, waste disposal and renovation, repair and recycling.5 Reversible logistics is also considered to be more complex to manage than advanced logistics6, as detailed activities in Reversible Logistics include the size, scope and impact on industry and the types of distribution channels7. Following the literature review, trends and some case studies in the world and in domestic research are identified, collection systems and directions for future and further research. The idea of ​​Reversible Logistics (RL) obviously shares similarities with the activities of the Circular Economy - repair, renovation, processing, recycling and reduction8. The purpose of Reversible Logistics (RL) is to reduce the raw material, the material for reuse and to respect the environment9, which fits into some activities and purposes of the Circular Economy (CE), although in a broader concept. The optimized Reverse Logistics (RL) demonstrated by world examples and different brands also lead to better supply chain visibility, leading to benefits. The optimized reverse logistics demonstrated by domestic examples Case Study 1 (for pellets) and Case Study 2 (for pallets) also lead to better supply chain visibility, leading to benefits

Logistics of passengers at the domestic airports

As statistics show, air travel is one of the most prevalent in this society of ours from day to day is increasing its use. Characteristic of air travel and transport is his speed but that speed depends from many factors. Some of these factors are: the speed and capacity of the aircraft, the speed of transport of goods to and from the airport warehouses them to planes, the speed of data processing for passengers and their luggage forwarding to the appropriate place for loading the plane, the speed of system transfer the luggage of a passenger to the appropriate place for loading the plane and the speed of the staff handled it. Hereafter will talk about all these factors which affect to a fast and successful air transport

Variable parameters are as follows: content of solid in pulp, underflow diameter, overflow diameter and inlet pressure. The cut point is determined by partition curve. The obtained mathematical model and the values of the coefficients make it possible to find the classifying cut point for variable factors

Mathematical modeling, programming in closed cycles of mineral technology

Modern mining contains two production activities: Exploitation of mineral resources and mineral technology. The first activity, using highly professional mining geological discovery on or off-balance sheet resources to dig up useful mineral mass, and the second, mineral technology (in the former terminology Preparation of mineral resources), table yeah processed, removing the beneficial mineral components in the final and commercial product that is interested in metallurgy, inorganic technology and other technologies and users of mineral resources. Mineral mining technology has physical character, because the processes that it applies, does not change the chemical composition of minerals and not disintegrate their crystal lattice, as is the case in metallurgy, chemical technology or hydro metallurgy, although the last one as combined process or independent process often used in mineral technology. Mineral technology basically accomplished through the following three basic operations: mechanical crushing and grinding, classification and concentration of diverse mineral components in relevant products: concentrates (commercial products) and waste (tailings). In modern mineral technology are more likely to go to the application programming packages and simulation of existing processes in order to provide a first step towards the eventual automation of technological processes in mineral technology. Applied computer programs to calculate the technological indicators in mineral technology, computer programs for the calculation of utilization efficiency of separation monomineral or polimineral raw materials, and computer programs to fully display hourly, daily, monthly and annual reports in the flotation concentration of minerals showed excellent results in the simulation of all processes in mineral technology

The Impact of Augmented Reality in Architectural Design Using Combined Method of Data Aggregation and Segregation

Augmented Reality (AR) enables digital information to be superimposed and integrated into our physical environment. With many of us now at home during a global pandemic, AR is a tool that can help us transform our immediate surroundings into learning, work, and entertainment spaces. AR can help to bring the outside world in a form of a virtual view with 3D objects in your living room or residential area using headsets that are capable of giving such experience. There is three things AR does very well: visualization, annotation, and storytelling. There are examples in each of these areas that are both timely in the current reality and which can be built upon once cultural institutions, schools and workplaces reopen their doors and bring them into one new mixed world of opportunities. Research documents of the evolutionary processes of buildings can illustrates the changes needed for the spatial environment, advances in civil engineering technology, the transformation of social norms, and adaptive standards for the new civil building policies. Augmented reality has built a platform that allows brands to offer unique and more accessible digital experiences, providing memorable moments for consumers. One of the main reasons that retail brands invest in the development of this technology lies in the idea of enabling consumers to make better and more informative product decisions. The merging of these interoperability structures between technology on the one hand and architecture on the other hand provides a systematic pre-solution for making the right decision when designing and investing in capital and socially useful buildings
