===== Fifth Attempt (15/12/2010) =====

from book //The craft of research//:

| **Topic** | I am studying | //properties of time series in remote sensing images//, | 
| **Research Question** | because I want to find out | //similar behaviors in these properties//, | 
| **Potential Practical Significance** | to understand/explain | //their relation to changes in land use/cover//. |

Trying to formulate a useful applied research problem:

| If my readers want to | //explain the relation of properties of time series to changes in land use/cover//, |
| would they think that they could do if they found out | //similar behaviors in these properties//? |

===== Fourth Attempt (08/12/2010) =====

| **Theme** | I am studying | //properties of time series in remote sensing images//, | 
| **Question** | because I want to find out | //whether they can be used to track changes in land use/cover//, | 
| **Motivation** | to understand/explain whether | //land changes are described by spectral changes//. |


===== Third Attempt (18/01/2010) =====

  * **What is the hypothesis base for the work?** 
//Classification methods based on decision trees are efficient to identify change signatures.//
  * **What are we trying to show or explain?**
//?//
  * **What is the scientific question to be answered?** 
// How to classify change signatures from  temporal and multi-dimensional remote sensing images using data mining approaches?  //

\\

| **Theme** | I am studying | //multitemporal datamining//, | 
| **Question** | because I want to create | //a method to classify change signatures from Sattelite Image Time-Series (SITS)//, | 
| **Motivation** | to understand/explain how | //?//. |

===== Second Attempt =====

  * **What is the hypothesis base for the work?** 
//It is possible to detect spectral trajectories of certain events, using image time series.//
  * **What are we trying to show or explain?**
//Region-boundary classifiers can split the feature space into detected spectral trajectories in time.//
  * **What is the scientific question to be answered?** 
//Multitemporal decision trees can overcome the curse of dimensionality?//

\\

| **Theme** | I am studying | //multitemporal datamining//, | 
| **Question** | because I want to create | //a method to recognize spectral trajectories in time//, | 
| **Motivation** | to understand/explain how | //certain events evolve//. |

===== First Attempt =====

  * **What is the hypothesis base for the work?** 
//It is possible to set a temporal signature to forest degradation.//
  * **What are we trying to show or explain?**
//Forest degradation are defined by smooth (light, slim, slight?), moderate and intense levels. With a set of snapshots from remote sensing images, one can develop an algorithm to detect such levels of degradation and to model its temporal signature.//
  * **What is the scientific question to be answered?** 
//Forest degradation can be modelled?//

\\

| **Theme** | I am studying | //forest degradation//, | 
| **Question** | because I want to create | //a method to find a temporal/spectral signature using snapshots of remote sensing images//, | 
| **Motivation** | to understand/explain how | //this phenomena (forest degradation) triggers and develops//. |
