Temperature programmed desorption (TPD) is the method of observing desorbed molecules from a surface when the surface temperature is increased. When experiments are performed using well-defined surfaces of single-crystalline samples in a continuously pumped ultra-high vacuum (UHV) chamber, then this experimental technique is often also referred to as thermal desorption spectroscopy or thermal ...
A remote pickup unit or RPU is a radio system using special radio frequencies set aside for electronic news-gathering (ENG) and remote broadcasting. It can also be used for other types of point-to-point radio links. An RPU is used to send program material from a remote location to the broadcast station or network.
Tax deduction at source. Tax deduction at source (TDS) is an Indian withholding tax that is a means of collecting tax on income, dividends, or asset sales by requiring the payer (or legal intermediary) to deduct tax due before paying the balance to the payee (and the tax to the revenue authority). Under the Indian Income Tax Act of 1961, income ...
An annual government report offered a glimmer of good news for Social Security and a jolt of good news for Medicare even as both programs continue to be on pace to run dry next decade.
In physics, terahertz time-domain spectroscopy ( THz-TDS) is a spectroscopic technique in which the properties of matter are probed with short pulses of terahertz radiation. The generation and detection scheme is sensitive to the sample's effect on both the amplitude and the phase of the terahertz radiation. Fourier transform of the above pulse.
Tabular Data Stream. Tabular Data Stream ( TDS) is an application layer protocol used to transfer data between a database server and a client. It was initially designed and developed by Sybase Inc. for their Sybase SQL Server relational database engine in 1984, and later by Microsoft in Microsoft SQL Server .
Transparent data encryption. Transparent Data Encryption (often abbreviated to TDE) is a technology employed by Microsoft, IBM and Oracle to encrypt database files. TDE offers encryption at file level. TDE solves the problem of protecting data at rest, encrypting databases both on the hard drive and consequently on backup media.
Time-driven switching. In telecommunication and computer networking, time-driven switching (TDS) is a node by node time variant implementation of circuit switching, where the propagating datagram is shorter in space than the distance between source and destination. With TDS it is no longer necessary to own a complete circuit between source and ...
