Sentiment analysis, or opinion mining, is the process of extracting sentiment from documents or sentences, where the expressed sentiment is typically categorized as positive, negative, or neutral. Many different techniques have been proposed. In this paper, we report the reimplementation of nine algorithms and their evaluation across four corpora to assess the sentiment at the sentence level. We e

This licentiate thesis examines the development of internationalization of production in Kazakhstan and its economic implications over the period 1991-2010. The main objectives of the thesis are to investigate the role of foreign investment and TNCs in the economic growth of Kazakhstan since its independence in 1991 and onward, to explore the motives that foreign enterprises have for investing in

This paper presents a fast, pipelined and scalable hardware architecture for inverting complex valued matrices. The matrix inversion algorithm involves, a QR-factorization based on the squared Givens rotations algorithm, the application of a recurrence algorithm for inversion of an upper triangular matrix R, and a matrix multiplication of R-1 with Q. We show that traditional triangular array archi

The number of electrically driven loads in a modern vehicle is constantly increasing. Many loads that former were mechanically driven will in the future be driven by electricity. This implies that a number of electronic systems have to be packed together in the limited space in a vehicle. When different electronic systems are placed close to each other, there is always a risk for electromagnetic i

Popular Abstract in Swedish Olika arter av stora växtätare lever på platser spridda över nästan hela jordklotet. På många av dessa platser samlar vi människor data för att kunna skatta storleken på deras populationer. Anledningen till att detta görs varierar från plats till plats, det kan till exempel vara för att djuren är utrotningshotade, för att kunna bedriva nöjesjakt eller för att begränsa aLarge herbivores are monitored for various reasons in many areas around the world. Data from such monitoring can be of varying degree of detail and extent. Several studies have shown that we need extensive amounts of data with a high degree of detail to be able to understand anything from it. Nevertheless, data in the less detailed form of annual censuses of large herbivore densities and weather i

The increasingamount of test data needed to test SOC (System-on-Chip) entailsefficient design of the TAM (test access mechanism), which is usedto transport test data inside the chip. Having a powerful TAM willshorten the test time, but it costs large silicon area to implementit. Hence, it is important to have an efficient TAM with minimalrequired hardware overhead. We propose a technique that make

This paper reports on the challenges computer forensic investigators face in relation to collaborative decision making, communication and coordination. The opportunities, operational environment and modus operandi of a cyber criminal are considered and used to develop the requirements in terms of both skill sets and procedural support a forensics investigator should have in order to respond to the

Optical properties of human whole blood were measured in vitro, at 633 nm with a double integrating sphere set-up, The blood was kept at constant flow through a flow cell while slowly heating the blood from approximately 25 degrees C to 55 degrees C in a heat exchanger, The results show a small but distinct decrease in the g-factor of 1.7 +/- 0.6\% and a similar increase in the scattering coeffici
