Trådløse signaler med modulerede og pulserende radioogmikrobølger er en ny form for luftforurening, og strålernerammer os døgnet rundt fra alskens sendere. Vi deltageralle i et globalt trådløst eksperiment!Stråler kan ikke ses, høres eller mærkes af de fleste, mende er en helbredstrussel for sårbare grupper som gravide,børn og el-overfølsomme mennesker.Det kan være nødvendigt med afskærmning mod stråler.Det må være ansvarspådragende, når WHO og Sundhedsstyrelsenfrasorterer dokumentation fra biofysisk forskningom biologiske skadevirkninger og accepterer ”no risk”propaganda ud fra manipuleret kræftmobilforskning.Sundhedsstyrelsen svigter befolkningen og især sårbare grupper,når der undlades forebyggelse af skadevirkninger vedbestråling. Der skal forebygges Nu!Det trådløse marked udbygges og styres af EU direktiverog forordninger, og lige nu gælder det mobile bredbåndssenderesom WiFi og Wlan, der giver internet adgang.Vi borgere kan ikke indhente oplysninger om, hvor dissesendere sættes op i kommunen, men selvfølgelig skal vivide, hvilke bestrålinger vi udsættes for, og hvor vi bestrålesfra.Børn skal ikke bestråles med mikrobølger i hverken skoler,daginstitutioner, tog eller busser.Der findes allerede el-overfølsomme miljøflygtninge!

Dagligt fristes vi af store annoncer om trådløse produkter. Med mobile bredbånd kan der surfes på nettet med smartphones og en bærbar computer, og de unge føler sig usårlige.Døgnet rundt udsættes vi for trådløs forurening. Er trådløse markeder vigtigere end sundhed og miljø? Vi misinformeres om sikre grænseværdier, som ikke findes. Vi fodres med forskningsskabte myter, fakta frasorteres og lægelige advarsler ignoreres.Det er på høje tid med forebyggelse. Børn kan ikke beskytte sig selv imod en usynlig og ukendt fare.

Retention time is an important phenomenon in dynamic random access memory for data storage operation. The storage capacitor is solely responsible for charge storing mechanism. The overall action is control by word line and bit line. It is also responsible for sensing, monitoring and data storing operation. Normally the availability of inexpensive leakage reduction technique is the backbone of any dynamic random access memory wherein the valuable sense information is deposited in storage capacitance in electric charge form. Since there is no option available for replenishing the electric charge on storage capacitor to prevent loss of information or data. One of the most acclaimed and accepted schemes toward effecting high retention time is by incorporating the leakage reduction technique which has becomes a part of dynamic random access memory. Semiconductor memory finds its application in almost all the electronics fields comprises data sensing, monitoring and data storing operation. In computer, tablet, cell phones, real time data acquisition system, healthcare, military and many more. In most of these applications there are requirements of data sense, preserve and processing in real time operation. In other words, this selection of memories based on the types of data stored in semiconductor memory i.e. temporary or permanent in many demanding applications. But leakage current play vital role after data storage operation in semiconductor memories. Due to leakage current there may be chances of loss of information and it affects the system performance. Hence a leakage reduction technique proves to be an excellent alternative with memory circuit for minimized the leakage current.

In the vast blue ocean, ships of different navies operate far from each other and are generally not in visual range. However, a ship can be uniquely identified based on a number of emissions that are characteristic to each and are called signatures. These include acoustic signature from machinery and flow, heat or infrared signature from exhaust, radar cross section from hull surfaces, magnetic signature from hull material, electric signature from corrosion protection systems etc. These signatures are used by surveillance and tracking sensors for attacking ships in general and warships, in particular. Survivability at sea requires management of all platform signatures to produce a net effect of reduced vulnerability. Anti-ship missiles pose the greatest threat to ships at sea. Prior to the Second World War, studies were carried out in parallel on the use of radar and infrared seekers in missiles for detection, identification and homing. For the materials available in the 1940s, radar seekers gave better results and hence, have become the standard fit. Over the years, advances in material sciences have improved the capabilities of infrared seekers and today, missiles have several guidance/seeker options that include radar, electro- optical camera and infrared imaging. Infrared homing is preferred for terminal guidance because of its inherent immunity to jamming techniques. A stealthy naval platform remains undetected and therefore can be deployed closer to the target to fulfill its mission with lesser risk of damage and associated causalities. Signatures used for ship detection include both underwater and above water. Signatures used by underwater weapons like torpedoes and mines are acoustics, magnetics, wake homing and extremely low frequency emissions (ELFE). Anti-ship missiles use above water signatures that include laser cross section (LCS), radar cross section (RCS), air borne noise and infrared (IR).

L'Organisation des Nations unies pour l'alimentation et l'agriculture prévoit que le monde aura besoin de 70 % de nourriture en plus d'ici 2050 en raison de l'augmentation de la population, de la diminution des terres agricoles et des ressources naturelles limitées.

This book in the field of distributed control system (DCS) and software architecture addresses key issues like hardware and software modularity and platform dependency. The hardware and software complexity in DCS increases with the number of devices and the types of communication standards and interfaces used. Hence, to minimize the complexity in the design of DCS, there is a need for modular hardware architecture. Similarly, to minimize software complexity, there is a need for modular software architecture. Also, there is a need to accommodate and integrate various types of hardware devices that can support different applications, as most DCS are platform-dependent and application-specific. Therefore, to resolve these issues, this book aims to explain different software architecture styles for distributed control systems. The specified architecture suggests modularity in the design to find similar attributes, reducing design time, cost, and risk of errors. To conclude, the Layered Software Architecture for HDCS is introduced and described in brief.
