3 g huawei ran resource monitoring and management recommendedMery Koto
The document discusses monitoring resources in a Huawei WCDMA network to avoid congestion and blockages. It describes monitoring resources at the NodeB and cell levels like CE cards, licenses, OVSF codes, power levels, and Iub bandwidth. Counters are presented to monitor traffic, KPIs, resource usage, and rejections due to congestion. The resource consumption of different services is also analyzed to understand network characteristics and identify if resources are sufficient for desired services.
Traffic congestion occurs when traffic demand exceeds road capacity, resulting in slower speeds and longer trip times. It is a major source of frustration for motorists and reduces travel speeds. The main causes of congestion are high traffic volumes, inadequate infrastructure, and irrational urban planning. Congestion leads to economic losses from wasted time and increased fuel costs, as well as environmental issues from higher emissions. Potential solutions involve improving road infrastructure, implementing smart urban planning, managing supply and demand through techniques like road pricing, and using traffic management strategies.

Mixed approach for scheduling process in wimax for high qoseSAT Journals
Abstract
WiMAX(worldwide interoperability for Microwave Access) networks are the networks which are responsible for providing many services like video, data and voice. The WiMAX technology satisfies the modern need of broadband internet through wireless access. For managing all these services through WiMAX, IEEE802.16 gives QOS (Quality of Service) parameter. In WiMAX, a fundamental challenge is to achieve high QOS so that various parameters like waiting time, end to end delay can be minimized and other parameter like execution time and network utilization etc. To obtain high QOS there is scheduling algorithm which is implemented at the base station and subscriber stations. In this paper we discuss scheduling algorithms and also compare the parameters (waiting time, turnaround time, execution time, packet drop age and packet delivery). We purpose a scheduling algorithm which is combination of greedy latency, distance calculation of user from base station, calculate the burst time and apply SJF on that burst values.
Keywords: WiMAX, QOS, IEEE802.16, Scheduling, FCFS (first come first serve), SJF(Shortest job First), Latency.

CHINA’S GEO-ECONOMIC OUTREACH IN CENTRAL ASIAN COUNTRIES AND FUTURE PROSPECTjpsjournal1
The rivalry between prominent international actors for dominance over Central Asia's hydrocarbon
reserves and the ancient silk trade route, along with China's diplomatic endeavours in the area, has been
referred to as the "New Great Game." This research centres on the power struggle, considering
geopolitical, geostrategic, and geoeconomic variables. Topics including trade, political hegemony, oil
politics, and conventional and nontraditional security are all explored and explained by the researcher.
Using Mackinder's Heartland, Spykman Rimland, and Hegemonic Stability theories, examines China's role
in Central Asia. This study adheres to the empirical epistemological method and has taken care of
objectivity. This study analyze primary and secondary research documents critically to elaborate role of
china’s geo economic outreach in central Asian countries and its future prospect. China is thriving in trade,
pipeline politics, and winning states, according to this study, thanks to important instruments like the
Shanghai Cooperation Organisation and the Belt and Road Economic Initiative. According to this study,
China is seeing significant success in commerce, pipeline politics, and gaining influence on other
governments. This success may be attributed to the effective utilisation of key tools such as the Shanghai
Cooperation Organisation and the Belt and Road Economic Initiative.
Optimizing Gradle Builds - Gradle DPE Tour Berlin 2024Sinan KOZAK
Sinan from the Delivery Hero mobile infrastructure engineering team shares a deep dive into performance acceleration with Gradle build cache optimizations. Sinan shares their journey into solving complex build-cache problems that affect Gradle builds. By understanding the challenges and solutions found in our journey, we aim to demonstrate the possibilities for faster builds. The case study reveals how overlapping outputs and cache misconfigurations led to significant increases in build times, especially as the project scaled up with numerous modules using Paparazzi tests. The journey from diagnosing to defeating cache issues offers invaluable lessons on maintaining cache integrity without sacrificing functionality.

The CBC machine is a common diagnostic tool used by doctors to measure a patient's red blood cell count, white blood cell count and platelet count. The machine uses a small sample of the patient's blood, which is then placed into special tubes and analyzed. The results of the analysis are then displayed on a screen for the doctor to review. The CBC machine is an important tool for diagnosing various conditions, such as anemia, infection and leukemia. It can also help to monitor a patient's response to treatment.
