An Ackerman steering linkage for short wheelbase, four-wheel vehicles has been developed. The linkage coordinates the steering angle of each wheel through a range of 180 degrees with minimal misalignment between wheels. Control of steering angles is accomplished using a single linear actuator. Control complexity is lower compared to four-wheel systems using individually controlled steering actu...

For $n=2^k$, let $S$ be an $n x n$ matrix whose rows and columns are indexed by $GF(2)^k$ and, for $I,j \in GF(2)^k$, $S_{I,j}={I,j}$, the standard inner product. Size-depth trade-offs are investigated for computing $Sx$ with circuits using only linear operations. In particular, linear size circuits with depth bounded by the inverse of an Ackerman function are constructed, and it is shown that ...

this paper deals with the behavior at infinity of solutions to a class of wave equations with nonlinear dampingterms defined in a semi-infinite cylinder. the spatial behavior of solutions is studied and an alternative ofphragmén-lindelöf type theorems is obtained in the results. the main point in the contribution is the use of energy method.

Interstitial granulomatous dermatitis (IGD) with arthritis is a new histological entity first described by Ackerman et al in 1993 [1]. Herein we report a case of IGD with prominent neutrophilic infiltration. A 57-year-old man was referred to our clinic with persistent, systemic, pruritic erythema and papules of four years’ duration. Psoriasis vulgaris was diagnosed and the patient was treated w...

although ‘allāma ḥillī and shaykh anṣārī have pointed out the feature of confirmation (iḥrāz) in some of the practical principles, its refinement has been one of mīrzā-yi nā’īnī’s initiatives. he divided the practical principles into “confirming and non-confirming. the confirming principle determines the practical duty of the religiously ccountable (mukallaf) in view of reality, such as: istiṣḥ...
