Precoding of Broadband Multiple-Input Multiple-Output Systems
ISBN: 9783639324938 / Angielski / Miękka / 2011 / 152 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. MIMO technology promises significant capacity improvements that lead to an efficient use of the radio frequency spectrum. To achieve its anticipated multiplexing gain and meet the requirements for higher data-rate services, existing broadband systems are based on OFDM or similar block-based techniques. These techniques are afflicted by poor design freedom at low redundancy, and are known to suffer badly from co-channel interference (CCI) in the presence of synchronisation errors. Non-block based approaches are scarce and do not require a guard interval; therefore can achieve higher...

Relativistic Gravity and Compact Binary Observations
ISBN: 9783838369556 / Angielski / Miękka / 2010 / 224 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Since binary pulsars represent a natural laboratory for testing relativistic field theories, it was interesting to study the problem of two bodies, in a strong field regime. Hence, this book is not only a complete review of the work done on binary pulsars but also, it includes an important step towards a more general solution to the problem of the strong field of two bodies; which is still far beyond the reach of researchers. This is done by modifying Curzon solution to describe the field of binaries. A more general formula for red-shift and Shapiro time delay were derived including...

Size and Chemistry of Particulate Matter in Cairo's Atmosphere
ISBN: 9783659463051 / Angielski / Miękka / 2014 / 200 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. This book describes the work carried out by the author to characterise suspended particulate matter (SPM) in Cairo's atmosphere. The TSP (total suspended particulate) and the size fractionated PM10 (inhalable particulate matter) were collected at an urban area in Cairo. The particulate matter collected at each size category was then chemically analysed for major water-soluble species (sulfates, nitrates, chlorides, and ammonium) and heavy metals (lead, nickel, chromium, manganese, and zinc). The annual mean PM10/TSP percentage was found to be 27.28% which indicates that particulates in...

Privacy and Practicality of Identity Management Systems
ISBN: 9783639380255 / Angielski / Miękka / 2011 / 264 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. The last few years have witnessed a significant growth in the number of identity management solutions. Because of the nature of the information that is handled by such systems, and because of their potential ubiquity, privacy and practicality issues are of great importance for such schemes. This book aims to provide an academic overview of the concepts of identity and identity management. It focuses on two categories of identity management systems, namely Information Card-based (ICIM) and Federated identity management systems. In addition to that, two novel schemes to enhance the...

Reyyan's Penance
ISBN: 9781483413792 / Angielski / Twarda / 2014 / 220 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych (Dostawa przed świętami) Reyyan is just eleven when the Soviets torture and execute his beloved elder brother in front of him and his mother. Devastated by the loss of her firstborn, she too gives up life moments later, leaving Reyyan an orphan. After the Soviets withdraw from his Afghan village, Reyyan's faith in goodness unravels, forcing him to fend for himself, and in so doing, caring little for others. Eight months later, Reyyan is adopted by his wealthy Afghan-American aunt, who is intent on protecting her sister's last memory. Under lax supervision and in response to his loss, Reyyan rebels into a playboy who...

Detection MIMO 5G Mobile in Communications System
ISBN: 9786206166573 / Angielski / Miękka / 52 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. The 5G spectrum sensing process is used for detecting signals in a given frequency range. It is an essential aspect of 5G networks and allows them to identify the available spectrum resources and configure their communication networks accordingly. The lack of spectrum is a major problem in the telecommunications industry. Spectrum is a finite resource, and it is becoming increasingly difficult for telecommunications companies to acquire enough spectrum to meet the growing demand for data services. This lack of spectrum can lead to higher prices and slower speeds for consumers, as companies...

Replacement of Induction Motors with Synchronous Motors
ISBN: 9783659472855 / Angielski / Miękka / 2013 / 64 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Most industries use induction motors for their applications (i.e. compressors, pumps, etc.) and these types of motors consume more reactive power. As a result, these industries either have to pay an additional cost for this power (Var), which produces more losses in the network, or they have to correct their power factor. Most of the industries prefer to correct their poor power factor by insulating a capacitor bank across loads for Var compensation. The selection of synchronous motor is basically to maximize the efficiency and reduce the penalty cost, or even the cost of the correction power...
