Passive Electronically Scanned Array (PESA) and the Active Electronically Scanned Array (AESA) are basically same in technology and principles of operation , both systems are capable of steer its beam Electronically through utilization of Phase Shifter hence it could be made in fully solid state configuration where no moving parts required (like APG-77 Radar on F-22 or Zhuk-AE Radar onboard MiG-35) they're only differs in source of Radio Frequency (RF) source The AESA uses multiple numbers of Radiating Elements where each of them have their own Transmitter and Receiver Module, making the Antenna where those modules located become "active" because it can Radiate by itself While the PESA system uses common RF source that usually found in conventional Radar like Klystrons, Magnetrons and Travelling Wave Tubes (this one especially, most common in Airborne Application like Fighter Radar). In Terms of Advantages the AESA system is typically better than PESA because of following factors : 1.because the Antenna Elements contain its own Transmitter and Receiver modules and located Right behind the Radiator, it would have lower or even No accidental loss , unlike her PESA sister which still require a connection to be made between its RF source to Radiating elements , incidental loss may occur. 2. High fault tolerance, failure of some modules will not hamper the operation of Radar (typical AESA Radar may contain 100++ Elements) however the entire device would fail if the failure occurs in 10% of total module counts.

3.No Single Point Failure , since basically each modules in active Version contains its own transmitter and Receiver modules, the passive device however since it still use single Transmitter device like Traveling Wave tube , failure of the transmitter may hamper the RADAR operations

EDIT- Bit improvements and adding single point failure in previous answer

Just to help point the above answer at the questions Passive systems have a single point of failure in its transmit devices (Travelling Wave Tubes,Wave Guides, Microstrips and Power Dividers as well as Antenna Feed System) . Active antenna do not have a single point of failure and a meant to degrades performance gracefully except probably malfunctions in its tapering systems or when the beam is steered in very high deflection angle which will reduce antenna effective Area, increase beamwidth hence reducing gain an compromise detection range. Active versions are much more flexible as phase can be varied in each or a groups of Radiating elements to create different waveforms or beamshapes .

Poinsettia is from New Latin. It was named after Joel R. Poinsett, an American diplomat, who died in 1851.

A genuine, good person believes that God created him or her, and they believe that God is One and has no partners. So they don't say that anyone is like God in anyway. They admit and acknowledge what they are. We are simply creations in need of our Creator every second. There are two kinds of people: Good guys and Bad guys. The genuine person asks God to make him or her one of the good guys. And the good guys do fight the bad guys, but some times in very subtle positively clever ways. aicp

1. Simplicity-Techniques for lexical analysis are less complex than those required for syntax analysis, so the lexical-analysis process can be sim- pler if it is separate. Also, removing the low-level details of lexical analy- sis from the syntax analyzer makes the syntax analyzer both smaller and less complex.

2. Efficiency-Although it pays to optimize the lexical analyzer, because lexical analysis requires a significant portion of total compilation time, it is not fruitful to optimize the syntax analyzer. Separation facilitates this selective optimization.

3. Portability-Because the lexical analyzer reads input program files and often includes buffering of that input, it is somewhat platform dependent. However, the syntax analyzer can be platform independent. It is always good to isolate machine-dependent parts of any software system.

An array is a container object that holds a fixed number of values of a single type. ... Each item in an array is called an element, and each element is accessed by its numerical index. As shown in the preceding illustration, numbering begins with 0. The 9th element, for example, would therefore be accessed at index 8.

Use ordinal numbers: 0, 1, 2, ...

Short interval scheduling is a technique that predates WWII. It was innovative then and even though not acknowledged as such, serves as the philosophical foundation for much of today's "lean, JIT, and agile manufacturing" concepts. Unfortunately there exists few cookbook-style references and to those of us who have actually deployed it successfully, it seems to enjoy a mystery about it ala... http://www.managers-net.com/short_interval_scheduling.html

At its essence, it looks at production capacity much in the same way we look at lot quantities today. In effect, "kan-ban'ing your productive capacity." It works best in process shops with a diverse series of products sharing similar processes. Similarly it is deployed in situations where the volumes are relative low. It is an excellent tool for project driven activities like construction, aircraft, and the like where you are deploying resources instead of materials. Again, the focus is on configuring the deployment of the capacity (in buckets) to meet the demand.

The unfortunate part of SIS is that it is best understood by doing, for that there is no substitute. I had it explained to me at least 100 times but it was not until I applied it a screw machine cutting tubes that I was able to understand the significance of both its simplicity and effectiveness. Try it and keep trying (and reading) until you hit that "aha" moment. Then you will understand. As they say in North Carolina, "Ain't nothing to it but to do it."
