This paper presents results of investigation on the effects of technology on the performance of the class E power amplifier circuit. A typical class E circuit has been designed and simulated, for a typical UMTS Tx frequency (1.95 GHz) and output power ( 27dBm). Three different technologies have been used (silicon BJT, CMOS and GaAs HBT) and several important parameters (output efficiency, power...

In this letter, novel class-F and inverse class-F power amplifier (PA) topologies were proposed, simulated, realized and measured for 2.7–2.9GHz frequency band by using Gallium Nitride high electron mobility transistor (GaN HEMT). Realizations are made on Rogers TMM3 dielectric material which has 0.381mm thickness and 3.27 dielectric constant. Proposed class-F and inverse class-F PAs have 10W (...

The following notes contain a computer simulation concerning a basic nonWalrasian equilibrium system, following the Edmond Malinvaud “short side” approach, as far as the price adjustment is concerned, and the sequential Hicksian “weeks” structure with regard of the temporal characterization. Two strongly heterogeneous classes of agents will be taken into consideration: the “rich” and the “poor”...

Pharmaceutical name: Bulbus Alli Sativi (da suan) Botanical name: Allium sativum Daily dose: 6-15g or 3-5 cloves in decoction, or added to the diet; raw garlic is more effective than cooked or dried forms. Notes: In 100 cases of amebic dysentery, a strong decoction of garlic was curative in 88% of the cases. Bulbs with purple skin were found to be more effective in this clinical study than thos...

In these notes we briefly review asymptotic results for the totally asymmetric simple exclusion process and the totally asymmetric constant-rate zero-range process, in the presence of particles with different priorities. We review the Law of Large Numbers for a second class particle added to those systems and we present the proof of crossing probabilities for a second and a third class particle...

Notes of my 14 ‘lectures on everything’ given at the 1995 Les Houches school. An introductory course in topological and conformal field theory, strings, gauge fields, supersymmetry and more. The presentation is more mathematical then usual and takes a modern point of view stressing moduli spaces, duality and the interconnectedness of the subject. An apocryphal lecture on BPS states and D-branes...

An annotated list of the Cuban fauna of Orthoptera is presented. For each species we include details of valid names, synonyms, type specimens (type category, sex, locality and depository), geographic distribution and bibliographic references. Clarifying notes are added, as well as comments on the species considered doubtful. A total of 140 species included in 62 genera, 31 subfamilies and 12 fa...

These working notes focus on the users’ actions in order to assist translations and on the usage of personal dictionaries (a feature which enables saving user added words). The special interest for this feature comes from a need to investigate to what extent users get actively involved in the query translation and contribute to overcoming the limitations of automatic translations. It is also ou...

Case description: This study used a case study investigation of a top-5 bank in Taiwan. The major data sources include the meeting notes of the FinTech investment task force and interviews with the team members. Co-opetition theory was adopted as the theoretical framework and interview questions were derived from the PARTS strategies in co-petition theory. The results relate to: (1) the strateg...

Multidisciplinary healthcare teams embedded into outpatient clinics enhance patient outcomes; it is therefore important that when medications are a focus of treatment in these clinical pharmacists included the team. At start 2019/2020 financial year, Princess Alexandra Hospital added 13 clinic pharmacist positions to their services. The aim this study describe results retrospective appraisal co...
