The development of a computerized battery simulator optimized for use in the ELPH 2.0 simulation environment
(Texas A&M University, 1996)
The objective of the research was to develop and integrate a computerized mathematical simulator of an electrochemical energy storage system into the ELectrically Peaking Hybrid (ELPH) vehicle computing environment. The ...
Design and testing of a sensorless switched reluctance motor drive with a custom integrated circuit controller
(Texas A&M University, 1996)
The switched reluctance motor (SRM) has become an attractive alternative candidate to conventional ae or dc motors for adjustable speed drive applications. The SRM drive system consists of a power converter and a control ...
Adhesion improvement of electroless copper depositions on titanium nitride by low temperature annealing
(Texas A&M University, 1999)
Due to the ever decreasing dimensions of the inter-level metallic interconnects, alternative metal deposition processes must be explored as the current processes (chemical vapor deposition (CVD) and physical vapor deposition ...
Joint sequence estimation and synchronization using wavelet pulses in a communication system
(Texas A&M University, 1994)
A new kind of baseband pulse is introduced in a receiver using nonsynchronized uniform samples. The pulse is an orthonormal wavelet generated by a discrete filter. Its performance is examined by applying a sequence estimation ...
20 MHz IF bandpass switched capacitor [] modulator using a high performance OTA with NCFF compensation scheme
(Texas A&M University, 2001)
Switched capacitor (SC) circuits are widely used in many applications because of their accuracy and ease of integration in CMOS technology. They are not suitable for operation in high frequencies because of the settling ...
Hierarchical implementation of a wireless communications system
(Texas A&M University, 2000)
Personal communications devices, such as the cellular phone, currently dominate the field of wireless communications. Product specifications such as weight, battery life, and transmission capacity pertain to consumer and ...
Analysis of power estimation techniques in CDMA systems
(Texas A&M University, 1999)
Power control is used in the reversed link to reduce the near-far problem in multi-user code division multiple access (CDMA) systems. Power estimation is one of the key aspects of the power control scheme. We compare and ...
Microfracture fabric of the Punchbowl fault zone, San Andreas System, California
(Texas A&M University, 1999)
The origin of fault zone structure is not completely understood. On the basis of mechanistic models of faulting, the characteristic internal structure of faults may largely be established early during growth of the fault, ...
An economical optical system design using phase diversity
(Texas A&M University, 1999)
The resolution of an incoherent imaging system is olden limited aberrations. Phase aberrations by phase arise from a variety of sources including atmospheric turbulence, misaligned optical and improper mirror figure. ...
QoS enhancement with partial state
(Texas A&M University, 1999)
Considerable work has been done in devising mechanisms for providing service guarantees within a network. These schemes can be broadly classified into two categories, schemes that require maintaining state for each flow ...
