In this note, steps in order to write a formula that gives the total number of subgroups of a finite abelian group are made.

Contact networks are often used in epidemiological studies to describe the patterns of interactions within a population. Often, such networks merely indicate which individuals interact, without giving any indication of the strength or intensity of interactions. Here, we use weighted networks, in which every connection has an associated weight, to explore the influence of heterogeneous contact s...

Third generation wireless system is based on the WCDMA access technique. In this technique, all users share the same bandwidth simultaneously but with different codes. So in Soft Handoff (WCDMA) new user will demand new OVSF codes. This behavior effectively reduces the total number of available OVSF codes in each cell. The effective available OVSF codes in each cell decreases as the percentage ...

The self-employed represent a significant percentage of the total number of Latin American workers. According to estimates of the International Labor Organization for 2016, they make up approximately 31% of the total number of workers, exceeding 40% in some countries. Thus, their inclusion in the pension systems is crucial for them to receive the same degree of protection in old age as dependen...

After 1948 the Romanian higher education entered a period of important developments, controlled by the communist regime, which meant thathigher educationinstitutions autonomy was severely obstructed, while politicalpurges affected the teaching staff and students alike. Nevertheless, new types of higher education were introduced and new institutions of higher education and specializations were e...

The author analyzes changes in the rate of migration and choice of destination among migrants from socialist countries in eastern and southern Europe to the United States and Canada during the period 1941-1990. "The data presented show that in the period in question the immigrants from the European socialist countries constituted only 2.9% of the total number of immigrants to the U.S.A. while ...

Recognizing the need for a valid and reliable way to measure outcomes of a program to promote multicultural awareness among nursing faculty and students, the authors developed a cultural awareness scale. In the first phase of the study, a scale consisting of 37 items was generated from a literature review on cultural awareness, sensitivity, and competence in nursing. A Cronbach's alpha reliabil...

This study examines the types of errors produced by Chinese learners of English when attempting to pronounce [T] in reading passages and presents a system for automatically detecting these pronunciation errors. The system achieves an accuracy of 79.8%, compared to the inter-annotator exact agreement rate of 83.1%. In addition, speaker-level scores based on the total number of correct production...

We study group chase and escape with some fast chasers. In our model chasers look for the nearest target and move to one of the nearest sites in order to catch the target. On the other hand, targets try to escape from the nearest chaser. When a chaser catches a target, the target is removed from the system and the number of targets decreases. The lifetime of targets, at which all targets caught...

We investigate Fano varieties defined over a number field, which contain subvarieties whose number of rational points of bounded height is comparable to the total number on the variety.
