چکیده

The Hilbert series of the Garsia-Haiman module can be written as a generating function of standard fillings of Ferrers diagrams. It is conjectured by Haglund and Loehr that the Hilbert series of the diagonal harmonics can be written as a generating function of parking functions. In this paper we present a weight-preserving injection from standard fillings to parking functions for certain cases. Résumé. La série Hilbert du module Garsia-Haiman peut être écrite comme fonction génératrice de tableaux des diagrammes Ferrers. Haglund et Loehr conjecturent que la série Hilbert de l’harmonic diagonale peut être écrite comme fonction génératrice des fonctions parking. Dans cet essai nous présentons une injection des tableaux vers les fonctions parking pour certains cas.

Autonomous Parallel Parking of a Car Based on Parking Space Detection and Fuzzy Controller

This paper develops an automatic parking algorithm based on a fuzzy logic controller with the vehicle pose for the input and the steering angle for the output. In this way some feasible reference trajectory path have been introduced according to geometric and kinematic constraints and nonholonomic constraints to simulate motion path of car. Also a novel method is used for parking space detec...

Nonsymmetric Schur Functions and an Analogue of the Robinson-schensted-knuth Algorithm

We exhibit a weight-preserving bijection between semi-standard Young tableaux and skyline augmented fillings to provide the first combinatorial proof that the Schur functions decompose into nonsymmetric functions indexed by compositions. The insertion procedure involved in the proof leads to an analogue of the Robinson-SchenstedKnuth Algorithm for skyline augmented fillings. We also prove that ...

Provision of car parking space in the residential neighborhoods: A development control challenge in urban areas

Although a substantial body of research concurs that most urban areas have a challenge in providing adequate car parking space, there is a scarcity in the literature on how conformity to planning standards that regulates the provision of car parking spaces may be analyzed. This study, therefore, examines the extent to which the planning standards that regulate compliance with the provision of c...
