  • - tro, håb og tech-giganter
    af Markus Bernsen
    118,95 - 205,95 kr.

    På få år er vores lille velfærdsstat blevet en forstad til Silicon Valley: Apple og Facebook bygger enorme datacentre i danske provinsbyer; Google har et tæt samarbejde med kommunerne; regeringen har nedsat et ”disruptionråd”, udpeget en ”tech-ambassadør” og lovet at gøre Danmarks til ”verdens mest digitaliserede land”. Samtidig forsøger en dansk modstandsbevægelse at tage magten tilbage fra tech-giganterne. De kan se, at digital overvågning, robotter og kunstig intelligens truer vores demokrati og frihed. Vi møder nørder, aktivister, hackere, dommedagsprofeter og cyborgs. Og vi finder ud af, hvad det er for nogle værdier, vi er i gang med at downloade fra USA.

  • - Manifest for frihed og fællesskab midt i en tech-tid
    af Lisbeth Bech Poulsen & Peter Westermann
    205,95 kr.

    Bogens grundsyn er præget en optimistisk tro på, at fremtiden bliver bedre. Men kun hvis politikerne træffer de rigtige – og store! –beslutninger. Når meget arbejde – også det intellektuelle – bliver overtaget af maskiner, får mennesker mere tid til nærhed og omsorg.Bogen er også et opråb og et politisk manifest. De positive konsekvenser af den moderne teknologi opstår nemlig ikke uden de ansvarlige politikeres indgriben. De politiske handlinger skal op i et tempo, der modsvarer den teknologiske udviklings. Det handler om omfordeling, både af penge, indflydelse og ejerskab.Fremtidens løsninger kan vi blandt andet finde ved nytænke nogle af fortidens succeser, fra andels- og fagbevægelse til overskudsdeling og folkeoplysning.Ti bud med flere konkrete løsninger, blandt andet til hvordan man kan indføre basisindkomst, regulere finanssektoren og skaffe mere fri tid og grøn omstilling, afslutter bogen.

  • - Consciousness, Empathy, and Reason in the Age of Intelligent Robots
    af Thomas Telving
    88,95 - 173,95 kr.

    Humanlike robots and digital humans are both fun and useful in many situations. But the more we interact with technology with human traits, the more we believe it to possess real human characteristics like consciousness and personality. As a new breed of artificial beings enters society on a large scale, many of us will start believing they deserve moral consideration and perhaps even rights.In this entertaining and humorously written book, Thomas Telving argues that even though the above scenario is close to inevitable, we should still do all we can to avoid it. Presenting us with thought-provoking future scenarios, state of the art scientific research, and engaging philosophical reflections, he shows us how to avoid some of the scariest pitfalls of human-like technology.“The rapid development in (embodied) artificial intelligence is all but certain to change our lives in the coming years. Using a philosophical framework, Thomas Telving convincingly presents a number of pitfalls following a large increase in human-robot interaction. He joins the important roboethic debate on what future we want to live in, and what it takes for humanity to keep the upper hand in shaping it.”— Tobias Larsen, PhD in Computational Neuroscience from the University of Bristol and senior data scientist at Oviva AG.“Artificial intelligence and advanced robots are increasingly used in science and society, and in many ways they outperform human capabilities. An important question is how our moral and legal stance towards robots will develop when their human likeness increases. In this entertaining new book Thomas Telving takes us through possible scenarios seen in a philosophical perspective. Enlightening, thought-provoking and highly recommended.”— Jacob J. K. Kirkensgaard, PhD, Associate Professor at the Niels Bohr Institute, University of Copenhagen.

    This book discusses the basic components of any alarm system.All alarm systems have two basic functions. First, they monitor their environment looking for a change such as a door or window opening or someone moving about in the room. Second, they alert the legal owner or user to this change. The system described in this book uses a scanning type software to detect intruders. It behaves like a guard dog, pacing up and down the fence line on the lookout for either an intruder or a familiar person. If you have an alarm key, you can disarm the system and enter.With the scanning method, the software is easy to write and explain. It can scan eight alarm zones plus two special fire zones in about one second.You don't have to be an electrical engineer to install an alarm system, just a decent carpenter, painter, and plasterer! Because this alarm system runs on 12 volts, you don't have to be a licensed electrician either to install it. The alarm system presented here uses Python software on the Raspberry Pi combined with some elementary electronic circuits. The code described in the book, as well as CAD files and a bill of materials for the alarm panel, are available for free downloading. The book provides the reader with examples of typical configurations coming straight from the author's experience. After reviewing the hardware components typically used in common alarm systems, the author shows how to plan one yourself.To implement a modular alarm, no matter if it is for a single house or for a business or restaurant, the book shows how to skillfully combine a Raspberry Pi with small auxiliary electronic circuits. These are not installation instructions but food for thought that will enable readers to find a solution to their needs.

    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.
