This research focuses on the development of advertising in interwar period Japan (between World War I and World War II) and the growing prevalence of the Modem Girl. As women with a certain aesthetic were popularized through advertisement campaigns, this aesthetic was disseminated to a wider audience and incited cultural change. For the purposes of this research, the rosmetics company Shiseido ...

1. ABSTRACT New waveform requirements are pushing the limits of traditional modem design techniques. Fortunately, modern Digital-to-Analog Converter (DAC) and Analog-to-Digital Converter (ADC) can achieve sampling rates in the GHz range. These new DACs and ADCs allow designers to directly synthesize channels that have bandwidths of more than 500 MHz+; allowing either wideband or multi-channel m...

Recently, several work related to channel assignment for MCN-type systems were reported. Wu et al proposed diverting traffic from the congested cells to the non-congested cells (Wu et al., 2001; Wu et al., 2004), which is achieved by relaying traffic through unlicensed frequency band, such as the industrial, scientific and medical (ISM) band. For iCAR (Wu et al., 2001; Wu et al., 2004), ad hoc ...

The following investigation of post secondary education will proceed via three subdisciplines of modem economic analysis: first, by way of well-known techniques used in the study of public finance (welfare economics); second through models connected with the economic theory of organization; and third through the approach of ʺpublic choiceʺ (the economics of politics). There are important areas ...

Global System for Mobile Communications (GSM) is one of the most commonly used cellular technologies in the world. One of the objectives in mobile communication systems is the security of the exchanged data. GSM employs many cryptographic algorithms for security like A5/1, A5/2 and A5/3. Even so, these algorithms do not provide sufficient level of security for protecting the confidentiality of ...

In this paper we evaluate the performance of data users in a GSM/GPRS system using queuing analysis and the QDB approach. GPRS has been introduced in GSM as a proposed data packet service over the air interface. Currently GPRS uses a fixed number of time slots, which are not shared with GSM voice users. Therefore the QoS of GSM users that are circuit switched is decreased. Here we propose a com...

The current researches and industries are looking forward to integrate different technologies to get a global technology that offers all of the intended services in a simple way. In this paper, a new communications system is proposed to integrate the use of GSM over the available satellites infrastructures. The proposed communications system could be used to facilitates and get benefits of both...

Genitourinary syndrome of menopause (GSM) causes significant symptomatic aggravation that affects the quality life (QoL). Vulvovaginal atrophy (VVA), hallmark GSM, is managed with topical non-hormonal therapy, including moisturizers and lubricants, estrogen application. Patients not responding/being unsatisfied previous local therapies are candidates for a noninvasive modality. Carbon dioxide (...
