فضای رقابتی به وجود آمده در صنعت گردشگری بین المللی، ضرورت توجه به توان رقابتی مقاصد را خیلی زود نمایان کرد. افزایش توان رقابتی که منجر به حفظ و افزایش سهم بازار می شود، هدف اصلی بسیاری از مقاصد گردشگری دنیا قرار گرفته است. از این رو پژوهش حاضر سعی کرده با استناد به تئوری های نوین رقابت پذیری گردشگری و استفاده از روش پیمایشی، یک رهیافت کمی را برای 1. ارزیابی شاخص های رقابت پذیری صنعت گردشگری و ...
Sufficient conditions are derived under which -ary partialand full-response continuous phase modulation (CPM) space–time (ST) codes will attain both full spatial diversity and optimal coding gain. General code construction rules are desirable due to the nonlinearity and inherent memory of the CPM signals which makes manual design or computer search difficult. Using a linear decomposition of CPM...
Conventional CPM signals employ information sequence with time-unlimited phase shaping pulse (PSP) to achieve power and bandwidth efficient transmission. On the contrary, information sequence using time-limited PSP was believed to produce power-wasting data-independent discrete spectral lines in CPM spectra, and was suggested to be avoided. In this paper, we revisit this problem and adopt the t...
Background: Because of fast rate of degradation and low mammalian cells toxicity the cypermethrin (CPM) is a wide used insecticide in domestic agriculture and in veterinary medicine applications. The compound exerts its pathological impact by down-regulating the antioxidant status. Therefore, current study was designed to evaluate the protective effect of vitamin E on CPMinduced apoptosis and n...
A multiple-input multiple-output (MIMO) wireless transmission system with continuous phase modulation (CPM) is considered. A novel MIMO CPM receiver with incoherent modulation is presented. The incoherent demodulation of CPM allows an uncomplicated handling of a frequency offset compared to coherent approaches requiring exact knowledge of the carrier frequency. Blind signal separation (BSS) is ...
BACKGROUND Research in animal models suggests that transcutaneous electrical nerve stimulation (TENS) and conditioned pain modulation (CPM) produce analgesia via two different supraspinal pathways. No known studies have examined whether TENS and CPM applied simultaneously in human subjects will enhance the analgesic effect of either treatment alone. The purpose of the current study was to inves...
There has been an increasing trend in the use of contralateral prophylactic mastectomy (CPM) in the United States among women diagnosed with unilateral breast cancer, particularly young women. Approximately one-third of women <40 years old are undergoing CPM in the US. Most studies have shown that the CPM trend is mainly patient-driven, which reflects a changing environment for newly diagnosed ...
Background: Safety, quality and effectiveness of Chinese patent medicine (CPM) are highly relevant to the manufacturing process. However, the level of manufacturing practice (GMP) for CPM as implemented in China is less reported in literatures. Therefore, the aim of this paper was to reveal the implementation status of GMP for CPM in China, in terms of implementation principle, implementation c...
