In a cellular network, signaling and data messages exchanged between network elements are an extremely valuable information for network optimization. The consideration of different types of information allows to improve the optimization results. However, the huge amount of information has made it very difficult for operators to process all the available information. To cope with this issue, in this paper, a methodology for processing cell and user connection traces to optimize a live cellular network is presented. The aim is to generate new performance indicators different from those supplied by manufacturers, taking advantage of the ability of complex event processing tools to correlate events of different nature. For illustrative purposes, an example of how a new performance indicator is created from real traces by complex event processing is given.

Dense deployment of cellular networks is leading to scarcity of communication bandwidth or what we call as channel. If compared to its wired counterparts, wireless cellular network have limited number of channels available, which gives rise to problem of efficient channel allocation. Here, in this piece of work, the main objective is to put an effort to improve existing channel allocation scheme. In earlier existing hybrid allocation scheme, the base station notifies about the hot-spots to the Mobile Switching Centre (MSC) and if MSC has available channels in its central pool then it satisfies the request. Now, the novelty of this work starts where central pool gets exhausted and request of channels from base station (BS) still arrives and is served by returning the unused channels by different cells back to MSC on its request. The simulation of this approach is expounded and evaluated over OMNeT++ in a scenario with fixed channel allocation and hybrid approach by varying the proportion of dynamic channels to total number of channels available and the effectiveness is evaluated in terms of Call blocked and Call dropped versus System load.

Sector Performance

This paper sets out to analyse and present trends in agriculture sector performance in Mozambique for the period 2000 – 2013 (with particular attention paid to the last three to four years of the said period). In the quest to attain this aim the paper empirically focuses on the significance of charting the performance of the sector against the baseline sectoral performance targets enlisted in the PNISA, CAADP Framework and SADC RISDP. There are ten key performance indicators that the paper delves ascertain the performance of the agriculture sector. The performance of this sector is pivotal because in Mozambique the agriculture sector is vital for economic development (contributes more than 20% to the GDP) also in meeting the Millennium Development Goal I (MDG I). The trend analysis led to the following main findings; the growth in agricultural GDP and the annual GDP growth of the country surpassed the CAADP target of 6% annual growth despite the fact that Government of Mozambique has vehemently failed to substantially invest in the agriculture sector to meet the CAADP 10% target of the total budget to agriculture. Agriculture productivity (land and labour productivity) in Mozambique is quite low, it is even lower than the average of the Low-Income countries in the region henceforth, the country has however been struggling to meet the agriculture production performance indicators. This is noted by the country's failure to meet both the SADC RISDP and Abuja Declaration fertilizer use targets of 50kg/ha and 65kg/ha respectively and the failure to meet the SADC RISDP irrigation target of doubling the area under irrigation to 7%. Consequently the country has failed to meet the SADC RISDP cereal production target of 2000kg/ha. The analysis also depict that the country has failed to meet the SADC RISDP livestock annual growth target of 4%. The implications of these failures have a significant bearing on the country's battle to offset poverty; the country's GHI is still alarming and the proportion of the population below the minimum dietary energy consumption is still high (41% on average) whilst the MDG I target stands at 28%. The major deduction from these findings is that there is a need for more concerted efforts in Mozambique to increase and refine agricultural growth investments; this can be carried out efficiently operationalising the PNISA to achieve the PEDSA, SADC RISDP and CAADP objectives.

Sector Performance

The Internet creates interesting opportunities for citizens to call public organizations to account. Government Web sites provide information and facilitate debates on public sector performance. An explorative study in the Netherlands indicates that citizens make little use of the opportunities to call public organizations to account. Openness, however, does have a direct effect: ‘public eyes’ stimulate government organizations to score better on performance indicators and comply with formal rules.

AbstractSince the 1980s, developing countries started to adopt telecom reforms due to pressures from international institutions. However, Middle East and North African (MENA) countries lagged in adopting such reforms. Even after introducing telecom reforms in MENA region beginning in 1995, not all countries became better off in terms of various performance indicators. Therefore, this paper empirically assesses the effects of regulation, privatization and liberalization reforms, as well as their simultaneous presences, on the sector performance in the telecommunication sector using a sample of 17 MENA countries for the period 1995–2010. We assume that different reforms are affected by institutional, political and economic determinants with respect to the level of democracy, the legal origin, the natural resources rents per country and the year of independence from colonization. We use IV-2SLS (Instrumental Variable Two-Stage Least Squares) estimation to analyze the effect of different reforms on telecom performance in terms of access, productivity and affordability in the fixed and the mobile sector. We find that privatization of the main incumbent operator and fixed-line market liberalization affect the sector performance negatively in terms of fixed access and affordability. Moreover, we find that the simultaneous presence of an independent regulator and a privatized incumbent helps to eliminate drawbacks on the sector performance resulting from privatization. However, the simultaneous presences of the other reforms in terms of regulation-competition and privatization-fixed competition do not help to improve the sector performance.

The earliest account of the contamination of electron microscope specimens by the deposition of carbonaceous material during electron irradiation was published in 1947 by Watson who was then working in Canada. It was soon established that this carbonaceous material is formed from organic vapours, and it is now recognized that the principal source is the oil-sealed rotary pumps which provide the backing vacuum. It has been shown that the organic vapours consist of low molecular weight fragments of oil molecules which have been degraded at hot spots produced by friction between the vanes and the surfaces on which they slide. As satisfactory oil-free pumps are unavailable, it is standard electron microscope practice to reduce the partial pressure of organic vapours in the microscope in the vicinity of the specimen by using liquid-nitrogen cooled anti-contamination devices. Traps of this type are sufficient to reduce the contamination rate to about 0.1 Å per min, which is tolerable for many investigations.
