Trådlösa Nätverk : säkerhet och GPU
Trådlosa nätverk är av naturen sårbara for avlyssning för att kommunikationen sker med radiovagor. Därfor skyddas trådlosa nätverk med kryptering. WEP var den första krypteringsstandarden som användes av en bredare publik som senare visade sig innehålla flera sårbarheter. Följden blev att krypteringen kunde förbigås på ett par minuter. Därför utvecklades WPA som ett svar till sårbarheterna i WEP.
H?GERPOPULISM OCH INRAMNINGAR AV FLYKTINGGRUPPER I POLEN
Recent studies about refugees have shown that there are differences in how refugees
are framed, depending on where they are fleeing from. Studies have also shown that
right-wing populism and refugee framing can be linked. With the theoretical framework
of Banulescu-Bogdans three frames and right-wing populism, this study examines how
polish politicians within the PiS party have framed refugees fleeing in 2015 in contrast
to refugees fleeing in 2022.The aim is also to analyze how and if right-wing populist
discourses are reflected in the frames.
Using framing analysis, nine statements from different PiS-politicians were analyzed.
The results show that the dominating frame towards refugees during 2015 was the
threat-frame, contributing to frame the refugees as a cultural threat and security threat.
The dominating frame used towards refugees 2022 was the victim-frame, contributing
to frame the refugees as deserving and worthy of help. Furthermore, right-wing populist
discourses were clearly existing in the framing of refugees in 2015. Discourses as ??us??
and ?? the other?? along with signs of nativism are reflected in the frames.
Att byta grupp : En studie om elevers och studenters perspektiv på icke självvalda grupper
The purpose of this research is to investigate the group constellation that is, what thoughts, feelings and sensations that arise when students and pupils change groups. The study will also affect students and pupils knowledge of why they should work in groups. Their perceived security will also be something that this study is looking for.The main questions of this study are:How does students and pupils experience the phenomenon of "group replacement"?What is considered to work or not work in the new group formations?The method that is used in this study is based on six qualitative interviews with students and pupils from three different levels of education. The target groups are college and high school students.
Att kommunicera eller icke kommunicera : Att utforma platscentrerade mobila sociala plattformar för att främja interaktion mellan främlingar
Communication between people who already know eachother, and who use a social online platform to do so, have been thouroghly studied for years. Thus, the majority of the people we connect with on a day to day basis are friends and acquaintances. As children we were taught not to talk to strangers, and as we grew older we learned to avoid people who act suspiciously. These and many other factors are part of the reason we avoid strangers, but are we doing so wrongfully? Studies have shown that there are many benefits in everyday interaction with strangers, some of which are an estimated increase in happiness and letting people seemingly forget about previous grievances.
Stadsmisson eller stadsvision En uppsats om Stadsmissionens roll i välfärdssamhället
Homelessness has always been and will always be a problem in every society. How should we organize the work and care for these people? There are three different types of welfare states, the liberal, the conservative and the social democratic. In the liberal welfare state the market is the supplier of the public good. In the conservative state the family and church and in the social democratic the state is the supplier of the public welfare.The Swedish welfare state has been the archetype of social democratic welfare with de principal of ?Folkhemmet? in focus.
Upplevelsen av ett självbestämmande- utifrån brukare och tjänstemän på ett särskilt boende.
Self- determination and autonomy of elderly people living in long- stay care homes is the forefront of discussion in the media and in society today. It examines the extent to which elderly people actually have the opportunity for self- determination and to what extent they have an impact and influence in their daily lives. A suitable way to look at how the quality of long ?stay care looks like is too look at the extent to which the user has self- determination.
The aim of our study was to examine how self-determination appears in long- stay care homes. We also talk about in what way the officials perceive self- determination and how elderly identify and perceive their right to self- determination and the importance it has for the individual.
The essay has been made with the help of interviews and surveys on a number of long-stay care homes in Skåne.
Arbetsterapeuters kliniska resonemang om individer med stressrelaterad ohälsa
Syftet med studien var att beskriva hur arbetsterapeuter inom primärvården kliniskt resonerar om individer med stressrelaterad ohälsa. Sju arbetsterapeuter verksamma inom primärvården deltog i studien. Data samlades in genom semi-strukturerade intervjuer och insamlad data analyserades genom kvalitativ innehållsanalys. Analys av data resulterade i tre kategorier ?förändring av klientens livssituation mot en bättre balanserad vardag?, ?Underlätta förändring genom ett gott samarbete? samt ?yttre faktorers betydelse på arbetet?.
Serialisering av API mellan PC och inbyggda system
Detta examensarbete behandlar problemet med att testa inbyggda system i kontorsmiljö. För att göra detta och därigenom kunna göra anrop på det inbyggda systemets API, måste detta anrop skickas som ett seriellt datapaket över en seriell kommunikationslänk som TCP/IP.Detta möjliggjordes genom att först upprätta en kommunikationslänk med protokollet TCP/IP, där användningen av POSIX-sockets tillämpades. För att packa ner och packa upp funktionsanropen till seriell data implementerades ett protokoll som följdes när detta utfördes. Hantering av data i samband med överföring över TCP/IP sköttes av ett protokoll vid namn BGSFP, ett protokoll som bygger på det tidigare protokollet TSFP..
Implementering av PostgreSQL som databashanterare för MONITOR
Monitors affärssystem MONITOR är under ständig utveckling och i och med detta ville man kolla upp huruvida PostgreSQL skulle kunna användas som DBMS istället för det nuvarande; Sybase SQL Anywhere. Examensarbete har därför bestått av en jämförelse hur PostgreSQL står sig jämte andra DBMS:er, en implementering utav en PostgreSQLdatabas som MONITOR arbetar mot samt ett prestandatest utav skapandet av databasen.I många avseenden verkar PostgreSQL vara ett alternativ till SQL Anywhere;Alla datatyper finns i båda dialekterna.Backup av data finns i olika utföranden och går att automatiseraEnkelt att installera och uppdatera.Ingen licensieringskostnad existerar.Support finns tillgänglig i olika former.Dock så är inte PostgreSQL ett bra DBMS att byta till i dagsläget då systemet inte fungerade på grund av att vissa uttryck inte översattes ordentligt samt att ingen motsvarighet till LIST existerar. Ännu större är dock problemet med tiden det tar att flytta data till en PostgreSQL-databas då det inte är intressant att lösa problem med funktioner i systemet om det ändå inte går att använda på grund utav att konvertering av data tar så lång tid som det gör..
Algoritmer för filtrering av MEMS-sensorsignaler
In order to measure the quality of the logs, one can with help of Fast Fourier Transform technique get the signals resonance peaks. With help of these peaks you can see whether the quality of a tree is good or bad. This report contains the work of a where a program has been developed to be able to process a vibration created by an automatic hammer hitting on a log of wood. From the processed signal the program should be able to show both the raw wavesignal and the processed measured data from the resonance peaks. Beyond the raw wavesignal and resonance peaks the program should also be able to control the automatic hammer.
