...CCDR's concept of operation. Force closure is that point which the combatant commander determines that an adequate combat-ready force is available. Force closure requires well-defined criteria by which unit commanders can measure their readiness. Assessment of combat power begins with established standards for readiness and is based on unit capability, rather than simple tallies of vehicles and weapon systems on hand. Readiness and reporting are inherently operational matters, normally handled through operations channels. Segments of RSOI 4-2.       RSOI operations are necessary for commanders to build combat power. The four segments of RSOI are—   Reception. Unloading personnel and equipment from strategic transport assets, managing port marshalling areas, transporting personnel, equipment, and materiel to staging areas, and providing logistics support services to units transiting the PODs.   Staging. Organizing personnel, equipment, and basic loads into movement units; preparing the units for onward movement; and providing logistics support for units transiting the staging area.   Onward movement. Moving units from reception facilities and staging areas to the tactical assembly areas (TAAs) or other theater destinations; moving non-unit personnel to gaining commands; and moving sustainment supplies to distribution sites.   Integration.

Unilateral Network

...Unilateral network is used widely in the study of circuit model. For network analysis, the bilateral network is of interest. In a two-port network analysis, the circuit under test is considered as a black box. Only the input and output voltages and currents are being examined. This information obtained is then used to obtained the network parameters which will simplify the analysis of a two-port network. This experiment consists of 2 parts: (i) Two-port network parameters and (ii) Transient response of a two-port network In the first part, the Y parameters and transmission parameters are to be determined. There are two networks (A and B) to be connected. The parameters’ values are determined experimentally for network A whereas for network B, the parameters are obtained using calculation. Then the 2 networks are connected in cascaded and parallel to determine the parameters experimentally. The results obtained are verified with the 2-port network principle. The experiment of transient response mainly covers the use of the storage oscilloscope to determine the first overshoot and undershoot. Besides, the oscillation period T is also determined. Furthermore, the effects of capacitor, inductor and resistor values on the circuit voltages response are examined. 2. OBJECTIVES 2.1 To measure the Y-parameters and transmission parameters of two-port networks. 2.2 To investigate the relationships between individual network parameters and two-port networks in cascade...

Effect of the West Coast Port Gridlock

...Erik H. Shirreffs Professor Harris IHR 380 17 March 2015 Effect of West Coast Port Gridlock From May 12, 2014 until February 20, 2015, the Pacific Maritime Association was in negotiations with the International Longshore and Warehouse Union in an attempt to come to an agreement on a new contract, which will keep the west coast port facilities in operation. The Pacific Maritime Association represents 72 cargo carriers, terminal operators and stevedores that operate 29 major U.S. ports spanning the west coast from Washington to Southern California (Pacific). The International Longshore and Warehouse Union represents approximately 42,000 members, which includes the 20,000 West Coast dockworkers that process over 340 million tons of cargo per year. This cargo represents over 12.5 percent of the nation’s Gross Domestic Product. The contract in dispute between the Pacific Maritime Association and the International Longshore and Warehouse Union expired on July 1, 2014. Since that time, the port facilities had continued to operate without a contract, but as time passed, pressure from both sides increased in order to reach an agreement. The Pacific Maritime Association claimed that the International Longshore and Warehouse Union had been engaged in a work slow-down that had increased the congestion at west coast port facilities. Although other factors such as increased holiday shipping demands and a shortage of trucks and trailers contributed to the congestion, according...

Holding Hands

...It might be chilly outside, but this snowy snap of a penguin couple holding hands is enough to melt even the coldest of hearts. The perfect pair enjoyed a romantic clinch, opting for a moment of solitude while dozens of other penguins gathered nearby. In fact, as one interloper approached the penguins, who looked almost like humans holding hands, appeared to give the freezing cold shoulder - and he continued trudging by. The heart-warming display of affection took place in Port Lockroy, a natural harbour in the Antarctic Peninsula. It was captured on camera by professional photographer Silviu Ghetie. What's going on here then? Oh, not you two again Get over yourselves! 'What are you two up to? Oh, holding hands again': Lonely heart approaches the couple and seeing they are only interested in themselves, moves switfly on The pair stand hand in hand appearing to stare out at the dramatic vista of the frozen Antarctic landscape. Their heads tilted slightly toward one-and-other, they look as if they are feeling the quiet drama that love brings to inner life. Then, still holding each other, they wander down to the icy waters and the rest of their friends. Photographer Mr Ghetie, 43, from Baia Mare in Romania, usually takes pictures of people but he couldn't resist snapping this magic moment while on a polar expedition. More...

...subnet within a site. The third level is the interface ID, this is a unique identifier for a particular interface. What this means for efficient routing, depends on the size of the association you’re running. If for example you’re running a smaller company, you can set all the bits in the Subnet ID to zero, which will in turn create a flat internal structure. This will reduce cost and maintenance. If you’re running a medium sized organization, you can optimize your address to use all the bits in Subnet ID, which will in turn give you more flexibility. Lastly, if you’re running a large company, you could create a multi-level hierarchy of subnets. So, in conclusion, using global unicast addressing allows for more elasticity when running a network. a) socket(); this function creates a new socket of a certain type, which is identified by an integer number. In addition to that, it allocates system resources to itself. b) connect(); the connect functions forms a direct communication link to a specific remote host that’s identified by its address via a socket. c) bind(); this function assigns a socket to an address. It’s used after the socket function, because when a socket is created, it isn’t assigned an address, so you must use the bind function before a socket is capable of accepting connections to hosts. d) listen(); This function is used on the server side and allows for a bounded TCP socket to enter it’s listening state. What this means is the socket is in a state where it’s ready...

Short and Medium Term Development

...Summary and Conclusion: The Port of Umm Qasr is an outdated, badly operated, insecure small port in Southern Iraq, which will increasingly limit the economic potential of the country. Access to the port is naturally limited by its shallow river location, high silt deposit rates, long approach and international boundaries. Umm Qasr activities are also limited by man-made obstacles such as wrecks, UXOs and minefields encroaching on its single, narrow channel. Despite these limitations, for the next 10 to 15 years Umm Qasr is clearly Iraq's most viable international port and one that is struggling to achieve a small fraction of its potential traffic. Numerous surveys of the port have stated that the currently operating equipment for cargo handling is inadequate for a vibrant, functioning port. However, the capacity of the port with its current equipment is substantially greater than what is being achieved, and additional equipment alone would have little impact on the port’s overall throughput or employment because the current operating systems and procedures are already incapable of productively utilizing and maintaining the port’s quite substantial current assets. In a port suffering from organizational chaos, even manual systems will permit substantially improved port efficiency. Training in systems to minimize cargo handling, documentation management, and customs handing, yard management and the other “software” of port management would not only consume...

...Proposed Sonadia Deep Sea Port – A Future Communication Hub of South-East Asia Introduction 1. Sea ports all over the world act as economic and communicational hubs. The leading sector of a country like Singapore is its deep sea port. Theoretically, deep sea ports can be defined as economic infrastructures at sea having enough space to accommodate and harbor large container vessels with adequate draft. 2. Bangladesh stands on the vertex of the Bay of Bengal, blocking sea access to the entire region lying north, north-east and north-west. This geostrategic advantage could offer Bangladesh real opportunities to play a major role in regional seaborne trade. 3. Sonadia, a small island near Maheshkhali, possesses enormous geographical potentials for developing a deep sea port. Proper utilization of this potential might turn Bangladesh into a communication hub of south-east Asia. With this backdrop, this paper would focus on the requirements of a deep sea port at Sonadia, its prospects as a regional communication hub and challenges on its way. Aim 4. To discuss the prospects of ‘Sonadia Deep Sea Port’ as the future communication hub of south-east Asia. Requirement of Sonadia Deep Sea Port 5. Chittagong and Mongla ports are unable to handle larger container vessels having more than 9.2 meters draft and 1500 TEU capacity. On the other hand, the annual growth trend indicates that in 2020, the total seaborne trade in Bangladesh may rise up to 70 to 80 million tons, which...
