Diuretic action in the kidney

The narrated movie takes the viewer from the human silhouette down subsequent levels of detail finally ending on the transporter proteins which are the direct targets of most diuretic drugs. The movie is intended to show the flow processes within the kidney including such aspects as filtration, reabsorption, and excretion in the nephron. It also shows the molecular sequence of ion transport, how the diuretics inhibit the reabsorption of sodium, and the subsequent effects on other ions

Signal Processing and Communications for Sensor Networks

Google Tech Talks
April 1, 2009

ABSTRACT

Presented by Martin Vetterli

A sensor network is a spatio-temporal sampling device with a wireless communications infrastructure. In this talk, after a short overview of the Center on Mobile Information and Communication Systems, where large scale ad hoc and sensor networks are being studied, we will address the following questions related to large sensor networks and their applications in environmental monitoring.

1. The spatio-temporal structure of distributed signals, with an emphasis on the physics behind the signals, and results on sampling.

2. The interaction of distributed source compression and transmission, with a particular focus on joint source-channel coding. This is the key theoretical question in sensor network signal acquisition and communication.

3. Applications in environmental monitoring, like for example tomographic measurements, and a description of a large scale environmental monitoring project in the Swiss Alps. This project, called SensorScope , has generated large and novel data sets for environmental questions, all available in open access.

This is joint work with T.Ajdler, G.Barrenetxea, H.Dubois-Ferriere, F.Ingelrest, R.Konsbruck (EPFL), and M.Gastpar (UC Berkeley). The work is sponsored by the Center on Mobile Information and Communication Systems (http://www.mics.org), funded by the Swiss National Science Foundation.

UOC – Managing the cost of mobile communication in Ghana – Michele Frix

“http://www.UOC.edu – Michele Frix – Managing the cost of mobile communication in Ghana

Information and Communication Technologies are spreading very rapidly at varying rates according to each specific technology. Globally, nearly one in four people are connected to the Internet. In the case of mobile telephony, incidence is higher, with two mobile phone lines for every three people.

Penetration, however, is not the same throughout the world. Although penetration in developing countries is lower, the impact of mobile telephony is being felt already and is gradually reaching wide segments of the population in both urban and rural areas. The new possibilities that are opening up in this new scenario need to be analysed carefully, assessing the advantages as well as the risks involved. Thus, along with capacities for communications and interconnections, it is also possible to find new interdependencies, both real and symbolic. It is not surprising that the arrival of ICT is more pronounced in many countries that have experienced high levels of emigration.

An analysis of this phenomenon can be carried out from different perspectives: sociological, anthropological, communication sciences, economics, etc. Each one would contribute a different perspective and emphasise specific research questions that, while each study’s central issue would be the same, they could be coordinated and integrated into a common perspective.

The objective of the conference is to promote debate about the influence that the spread of ITC, (specifically mobile phones and the Internet) may have on the social and economic development of Latin America and Africa and, in particular, amongst the most vulnerable segments of the population. The conference aims to review the status of this topic within a subject that needs further, in-depth, exploration. It also aims to stimulate debate about the key topics related to this new direction that a great many countries are just starting to follow.

The event seeks to embark on a joint reflection involving actors from developing countries and regions in Latin America and Africa in order to study what and how much is known about the real effects that communications technologies (especially mobile phones and the Internet) are having on the economic and social development of their populations. The participation of prestigious researchers representing different perspectives, disciplines and regions will provide a wide frame of reference for the current status of the issue.

Cell Site Analysis – a Brief Introduction

An introduction into Cell Site Analysis

Technical Background of Cell Site Analysis by Simon Steggles – Mobile Phone Forensics

Cell phones, (or Mobile phones) used today are transceivers which use little power. They combine both a transmitter and a receiver. Although most cell phones, (or Mobile phones), are used to provide a telephone service for the public, they are still radio transmitters and receivers. Because of this, mobile phones, (or mobile phones), behave in the same way that traditional radio equipment does. Mobile phones operate through networks, (which in the UK are run by O2, Vodafone, Orange and T-Mobile). These networks are GSM, (Global Systems for Mobile communications), and are built around an array of transmitters, receiving stations which cover nearly all of the United Kingdom. Many other countries follow this similar rule; however, they may have different networks run by different companies, (Verizon, AT&T etc).

These transmit and receive stations (or beacons), are also known as ‘Cell Sites’. Each cell site consists of multiple receivers and transmitters and of course the relevant aerials associated with each one. These sites are often on masts, can be sited above police stations, schools or other tall buildings, (giving clearer transmissions, therefore clearer line of site transmission).

Each cell site has a reference number and name. Using this information, one can state exactly the area of the cell site. From this we can pin point to a very small area if the suspect phone has been used in this area.

Whenever a mobile phone is ‘on’, it scans the radio frequencies assigned to it by its designated network provider, and then links up the cell that gives it the best coverage. This process is called registration, and is of course necessary for the networks so that they can direct incoming or outgoing calls to the correct phone. When travelling, (for example), a phone may move from one cell site to another. This is achieved by the phone evaluating the signal at all times, and switching over to the appropriate best one. This is also logged by the networks and is known as a ‘handover’. The handover also ensures a continuation of the call, rather than the requirement to redial every time a new better cell site is found.

Network providers positioned their cell sites after carrying out extensive testings on the frequency, geographical position, and potential transmission/reception hazards. Extensive maps of these tests are kept by the network providers, showing the specific cover of each transmitter and receiver.

Even when mobile phones are not executing a call, they are still logged on the network providers systems, ready for their next call/message. This information is not stored historically, however when a call is made or received, it is. When a phone is ‘live’ i.e. switched on and connected to the network providers, it is possible to track it by the non recorded records which get switched on manually.

Geographical locations can be specified for a mobile phone by referring to the call detail records, (CDR’s). This can give you information of which cell site was being used. From checking the records about the specific site in question, it is then possible to find out about if the aerial was a full 360 degrees, or an azimuth of 120 degrees, (these can vary). If the call was coming from aerial 3 on a cell site, then it is right to assume that the specific geographic location of that cell phone is now only a third or the original area it was thought to be in, (e.g. If a call was made from the south of a cell site, then it is likely that the mobile phone was within a reasonable, (varies) distance from the south of that cell site).

Things to take into consideration:

1. Cell Site Analysis is not a proven science. Even if a mobile phone was used in position A, to the south of a cell site, it doesn’t necessarily mean that the phone was actually there. It could well be anywhere up to a theoretical 35Kms away if all the cell sites between the phone and the used cell site had achieved maximum usage, (cell sites can only accommodate a finite amount of traffic at one time) or are not in service.

2. The cell site chosen is not necessarily chosen by the phone, it may be the network ‘re-directing’ the phone to a ‘not so busy’ cell site.

3. Geographical locations may also prevent the usage of a cell site, (large building in the way, dense woodland etc).

The latest system for mobile phones is 3G, (third generation). This relies on UMTS, (Universal Mobile Telecommunications System), a faster data transfer system using Duplexing technologies. In the UK 5 licenses were won for the ability to provide these services. These network providers are 3G Technologies, Hutchinson 3G, Orange, Vodafone, O2 and T-Mobile. Although a different style/type of service, UMTS is recorded in the same way as traditional GSM. Handover occurs in the same way between UMTS and GSM as GSM to GSM.
