1. 11. Integrated antenna switch for NB-IoT

   Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

   Författare :Fredrik Zetterblom; Yunus Dawji; [2018]
   Nyckelord :T R Transmit Receive switch; RF switch; integrated RF switch; Narrowband Internet of Things NB-IoT ; CMOS; frontend; Technology and Engineering;

   Sammanfattning : Transistors are used in all digital devices today. The demand of faster and smaller devices such as mobile telephones and computers constantly drives the develop- ment of smaller transistor technologies. Transistors can also be used in analog applications. Today there are commercial chips with both radio and digital sys- tems in the same package. LÄS MER

3. 12. Kontaktlös flödesmätning med trådlös dataöverföring : Undersökning av kostnadseffektiva system

   Uppsats för yrkesexamina på grundnivå, Mittuniversitetet/Avdelningen för elektronikkonstruktion

   Författare :Sonny Svensson; [2017]
   Nyckelord :Non-intrusive flow measuring; ultrasonic; water pipeline net-works; leakage detection; data logger; Kontaktlös flödesmätning; ultraljud; vattendistribution; läck-sökning; datalogger;

   Sammanfattning : Målet med undersökningen har varit att undersöka möjligheten att ta fram en kostnadseffektiv lösning för att mäta flöden i slutna rörsystem. Anledningen till att kontaktlösa metoder valts för arbetet är dess egen-skaper att kunna installeras utan att göra ingrepp i ledningarna eller på något sätt påverka det flödande mediet i dessa.

4. 13. Nonlinearity In Exchange Rates : Evidence From African Economies

   Master-uppsats, Uppsala universitet/Statistiska institutionen

   Författare :Ndey Isatou Jobe; [2016]
   Nyckelord :Nominal Exchange Rates; Linear Models; Random Walk Model; Smooth Transition Autoregressive Model; Linearity Tests; Unit Root Tests; Forecast Evaluation.;

   Sammanfattning : In an effort to assess the predictive ability of exchange rate models when data on African countries is sampled, this paper studies nonlinear modelling and prediction of the nominal exchange rate series of the United States dollar to currencies of thirty-eight African states using the smooth transition autoregressive (STAR) model. A three step analysis is undertaken. LÄS MER

5. 14. Different Digital Predistortion Techniques for Power Amplifier Linearization

   Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

   Författare :Ibrahim Can Sezgin; [2016]
   Nyckelord :DPD; Digital Predistortion; Forward Behavioral Modeling; Power Amplifier; Non-Linearity; Memory Effect; Volterra Series; Memory Polynomial; Generalized Memory Polynomial; Simplified Volterra Series; Augmented Complexity Reduced Generalized Memory Polynomial; Augmented Complexity Reduced Simplified Volterra; Technology and Engineering;

   Sammanfattning : Linearity and high efficiency are crucial requirements for any power amplifier. However, power amplifiers have high efficiency levels when they are in non-linear regions. To overcome this issue there have been many suggestions in literature, one of the most successful methods is digital predistortion method. LÄS MER

7. 15. Modeling the intronic regulation of Alternative Splicing using Deep Convolutional Neural Nets

   Master-uppsats, KTH/Skolan för datavetenskap och kommunikation (CSC)

   Författare :Johannes Linder; [2015]
   Nyckelord :Machine Learning; Deep Learning; CNN; CNNs; Convolutional Neural Networks; Convolutional Neural Nets; Neural Networks; Neural Nets; Synthetic Biology; Alternative Splicing; AS; Splicing; DNA Regulation; Synthetic DNA; Massively Parallel Library; Maskinlärning; CNN; CNNs; Convolutional Neural Networks; Convolutional Neural Nets; Faltning; Neurala Nätverk; Neurala Nät; Syntetisk Biologi; Alternativ Splicing; Splicing; AS; DNA; Massivt Parallellt Bibliotek; Syntetiskt DNA;

   Sammanfattning : This paper investigates the use of deep Convolutional Neural Networks for modeling the intronic regulation of Alternative Splicing on the basis of DNA sequence. By training the CNN on massively parallel synthetic DNA libraries of Alternative 5'-splicing and Alternatively Skipped exon events, the model is capable of predicting the relative abundance of alternatively spliced mRNA isoforms on held-out library data to a very high accuracy (R2 = 0.
